Licensing Exception Error when trying to establish an API-connection to Plunet

RWS oneword — Fri, 07 Aug 2026 10:43:44 GMT

At oneword, we are currently testing the automation of Trados projects using Plunet's Trados Project Automation API. However, it seems there is a problem with the verification of our licenses, as the attempt to use them is currently failing. Plunet Support has sent us the following message:

"The error does not seem to originate directly from DeepL or from the paths in the project template, but rather from the Trados license check itself: “Sdl.ProjectAutomation.FileBased.LicensingException”
A valid Trados Studio Professional license is required to use the Trados Project Automation API / FileBasedProject. In this case, the license is apparently being verified, but it is not accepted by Trados in this server/remote/domain environment.
More information here: https://developers.rws.com/studio-api-docs/apiconcepts/projectautomation/overview.html
"Please check whether your Trados Studio 2024 Professional license is authorized for this use."

Our Trados Studio 2024 version is: Trados Studio 2024 SR1 - 18.1.3.6657

Is it possible that there is a problem with our licenses here? We are not familiar with the specifics of the various license types and, unfortunately, cannot assist Plunet Support with this matter ourselves.

Do the implicit Windows Credentials work with the Studio 2024 SR1 CU4 API? For me it only works if I explicitly include the user name and password.

Daniel García Magariños — Tue, 07 Jul 2026 17:18:13 GMT

This is a continuation of a discussion I opened in the GroupShare developers forum because I think this actually is related to the Studio 2024 API.

community.rws.com/.../connection-to-groupshare-2020-sr1-cu12-not-possible-from-studio-2024-sr1-cu3-with-implicit-windows-credentials---works-if-the-user-explicitly-enters-user-name-and-password

I am beginning to suspect something has changed in the API. The error seems to be coming from this component:
Sdl.Desktop.Platform.ServerConnectionPlugin.TMServer.TranslationMemoryAdminstrationClientFactory.Create(String baseAddress, UserCredentials credentials, IServerConnectionService serverConnectionService)

In Studio 2022, I could connect to our TM Server in GroupShare with this code.

I used the Windows credentials of the current user without having to ask the user to enter them:

private void button1_Click(object sender, EventArgs e)

{
bool blWindowsAuthentication;
blWindowsAuthentication = true;

// Connect with URL and credentials
// TranslationProviderServer tmServer = new TranslationProviderServer(GetUri(txtServerURI.Text), blWindowsAuthentication, "", "");
TranslationProviderServer tmServer = new TranslationProviderServer(GetUri("">https://SERVERNAME"), blWindowsAuthentication, userName: null, password: null);
MessageBox.Show ("Connected");
}

private Uri GetUri(string _serverUri)
{
return new Uri(_serverUri);
}

Now exactly the same code gives this error:

System.NullReferenceException: 'Object reference not set to an instance of an object.'

Here is the stack trace with more details:

Source: Sdl.Desktop.Platform.ServerConnectionPlugin

StackTrace " at Sdl.Desktop.Platform.ServerConnectionPlugin.TMServer.InternalClients.TmServiceRestClientCreator.CreateRestClient(String baseAddress, ClientSettings clientSettings)

at Sdl.Desktop.Platform.ServerConnectionPlugin.TMServer.InternalClients.InternalRestClient..ctor(String baseAddress, ITmServiceRestClientCreator restClientCreator, IBcmToTransUnitConverter bcmToTransUnitConverter)

at Sdl.Desktop.Platform.ServerConnectionPlugin.TMServer.TranslationMemoryAdminstrationClientFactory.Create(String baseAddress, UserCredentials credentials, IServerConnectionService serverConnectionService)

at Sdl.LanguagePlatform.TranslationMemoryApi.TranslationProviderServer..ctor(Uri serverUri, Boolean useWindowsAuthentication, String userName, String password)\

at WindowsFormsApp1.Form1.button1_Click(Object sender, EventArgs e)

Could somebody test the code below and confirm that implicit Windows Authentication works for them? 

According to the SDK, this should work:

https://developers.rws.com/studio-api-docs/api/translationmemory/Sdl.LanguagePlatform.TranslationMemoryApi.TranslationProviderServer.html
useWindowsAuthentication

Whether to use Windows authentication. When n set to false, userName and password have to be specified. When set to true , either pass null for userName and password in order to log on as the currently logged on Windows user, or set userName to a domain-qualified Windows user name and password to the matching password to log on using basic Windows authentication.

Thanks!

Trados Studio 2026: Activating a file already open in the Editor does make it the active file

Josep Condal — Mon, 06 Jul 2026 12:08:42 GMT

In Trados Studio 2026 build 19.0.0.3043, when we try to make active an already opened file in the editor different than the one that is already active, the active file is not changed, that is, the call to EditorController.Activate(document) is ignored.

We also noticed the event hook EditorController.Opened is not firing the functions that subscribed to it (unlike the EditorController.Opening event hook that fires them fine).

This issue of the active file not being replaced is also reproducible in the Trados Studio 2026 UI with these steps:

In a Trados Studio 2026 with no files opened in Studio, go the Files view of a project and double click on any file to open it. (This works fine: the Editor view opens, and shows the file double-clicked file).
Go back to the Files view and double click on a second file, different from the first one. (This works fine: the Editor view opens, and has the second file as the active one).
Go back to the Files view and double click again on the first file. (This fails: the Editor view opens, but the second file is the active one instead of the first one).

Just for the record, none of the above behavior happens Trados Studio 2024. In step 3, Trados Studio 2024 correctly activates the first file. Also, in Trados Studio 2024 the EditorController.Opened event is fired and EditorController.Activate(document) is honored.

How to predefine Selected Fields settings for dynamically added server-based MultiTerm termbases during project creation?

Sophia Wessin — Thu, 25 Jun 2026 15:38:57 GMT

Dear Studio developer community,

We have recently updated our environment to Trados Studio 2024 SR1 CU3 (18.1.3.6657). Due to the change to the Selected Fields settings for termbases in SR1, the Selected Fields settings our users make in File > Options > Language Pairs > All Language Pairs > Termbases > Selected Fields are now ignored when they work on our translation projects because the Selected Fields settings of the project always take precedence. In our case, nothing is selected in the project's Selected Fields settings, so the RWS default fields are displayed in the Term Recognition window in the Studio Editor. We were told by RWS support that this behavior is by design. Due to the above issue, in order to help our users choose the correct terminology, we would need to predefine certain Selected Fields for all users. Since the SR1 change, this would usually be set in the project template and then apply to all projects created based on this template. But we have a custom-built project creation automation which creates local Studio projects based on centrally managed project templates and dynamically connects the correct server-based MultiTerm termbase (depending on the project’s language combination) only during project creation. So we cannot preset these settings in the project templates because the templates don’t actually contain a termbase entry.

I tried to find information about specifying the Selected Fields via Studio API, but I'm not sure I found the correct place in the Studio API documentation. I can't find the setting mentioned on the Adding Termbases page. The API release notes for Studio 2024 SR1 mention the new ShowInUI property for the DescriptiveField class - is that where our developer would need to specify which fields should be displayed to the users? Or is this only related to setting up a custom terminology provider, but not related to adding an existing provider to a project, and they would instead need to use another class/property?

We would appreciate more details about the API and/or code examples that could help us predefine these termbase fields. For example, on termbase level, we would need to enable the terminology domain ("component"), and on term level things like Gender, Abbreviation etc. (see attached screenshot).

Thanks,

Sophia

Does Trados 2024 API support parallelization?

Stelios Mathioulakis — Fri, 12 Jun 2026 08:03:56 GMT

Hi all,

Is parallel use of FileBasedProject and FileBasedTranslationMemory from multiple processes on the same machine, under the same Windows user, a supported scenario in the Studio 2024 SDK? I know this worked in previous versions but in one environment that I use 2024 I get the errors below when more than 1 worker is invoking my .exe at the same time:

The translation memory data file engine returned an error:
attempt to write a readonly database

The translation memory data file engine returned an error:
disk I/O error

The per-task projects and .sdltm files are in separate folders, so they don't collide on disk. These parallel executions all have different target languages, so there should not be any collision in theory.

So, has something changed in Trados 2024 in regards to running in parallel? Thank you

Trados Studio API (Import Server option for Groupshare Project Templates)

Bruno Ciola — Thu, 11 Jun 2026 10:17:08 GMT

Dear all,

As there is an issue with the project template upload in Trados GroupShare (hitlist settings are lost), I am looking for a way to automate the upload process via the Trados Studio 2024 API.
Is the project template "Import Server" feature exposed in the API? Do you have any information about this?

Regards,

Bruno

How to convert .sdlftsettings into .sdltpl?

Stelios Mathioulakis — Wed, 10 Jun 2026 13:26:00 GMT

Hello all,

Is there a standard way to turn an exported file type settings file (.sdlftsettings) into a project template (.sdltpl)? Ideally via the Project Automation API, rather than hand-editing the XML. Thanks!

Sequence of buttons on ribbons no longer kept after upgrading plugin from Trados 2022 to Trados 2024

Dino Azzano — Tue, 02 Jun 2026 12:48:49 GMT

Dear community,

I have a Trados Studio plugin that creates a RibbonGroup in the Home ribbon. This group features 9 buttons.

I have set the sequence in which the buttons should appear in the ribbon by specifying the ZIndex parameter, e.g.

[ActionLayout(typeof(ERibbonGroup), 10, DisplayType.Large)]

The highest index equals to the first position from the left.

This works reliably on Trados 2022 (2022 SR2 - 17.2.10.19084). However, we are now testing Trados 2024 (2024 SR1 - 18.1.3.6657), so I have updated the plugin according to RWS instructions (https://developers.rws.com/studio-api-docs/articles/hints_tips/Update_Plugins/how_to_update_plugins_to_trados_studio_2024_sr1.html?tabs=standard).

Even though no other change has been applied, the sequence of the buttons appears now random. At the very least, it does not respect the ZIndex parameter.

Has anyone experienced this issue and knows any solution?

Pushing HTML files for automatic Project creation in Trados

Jose Salas — Fri, 29 May 2026 20:21:19 GMT

Please see case CS0050244

This particular query concerns sending HTML files to Trados to automatically create a project using a certain template. We extract HTML files from an email campaign site and inject the translated versions back for automated population. The missing link to fully automate our workflow is getting Trados to automatically create a project with SDLXLIFF files.

Developing a Trados Plugin for Gemini / Vertex AI Integration

Tetsu Tetsu — Tue, 26 May 2026 08:37:23 GMT

Hi everyone,

My name is Sato. I'm looking to use Gemini translation (Vertex AI) within Trados Studio 2024. While plugins for Google Translate and OpenAI are already publicly available, I couldn't find one for Gemini, so I've decided to develop my own.

Regarding my development environment, I cannot use Visual Studio 2022, so I'm planning to use VS Code instead. However, I’ve run into an issue: the "developer hub" link on the following page appears to be broken, and I cannot find where to download the Trados Studio SDK.
developers.rws.com/.../setting_up_a_developer_machine.html

Could anyone point me to the correct link for the Trados Studio SDK, or share any insights on developing plugins using VS Code? (Also, please let me know if a Gemini plugin already exists!)

Lastly, if this isn't the right community to post this kind of technical question, I'd appreciate it if you could direct me to the correct forum.

Thanks in advance for your help!

Trados 2024 API problem only affecting Simplified Chinese projects

Mark Owens — Fri, 22 May 2026 13:31:27 GMT

Hi,

I have a API program which creates a Trados Studio project from a template.

The steps for the program are

Create project file
Add source files from a folder
Scan source files
Convert to translatable format
Analyse files
Add DeepL translation provider to project
Pretranslate
Analyse files

This program works without complaint for all target languages except Simplified Chinese.

In step 5, I see this message for each source file in the project:

The type initializer for 'Icu.NativeMethods' threw an exception.

In step 8, I see this message for each source file in the project:

The type initializer for 'Sdl.Core.LanguageProcessing.ICU2.WordBoundaryFinder' threw an exception.

In both analysis steps, the task has a closing status of "Failed".

Can anyone advise on how to cure this problem?

Thanks

Mark

How to create multiple translation projects based on Trados APIs by using many licenses at the same time to release concurrent cases

Flavio Sun — Mon, 27 Apr 2026 07:20:37 GMT

Hi,

I am a Trados user for SDL Trados 2019 and 2024 with licenses. I am writing automation exe based on Trados SDK API to make project automated.

When running the project, I find that in same time only one Trados License can be activated and only one Instance is running, for example, If two users want to create two translation projects at the same time, only one user can launch the Trados API-based exe, and the other user must be waiting for the license released.

So I WANT TO KNOW, How can I realize the cocurrent use? For example, I have 4 licenses, and It is possible for us to run 4 projects at the same time by calling the APIs.

Thansks,

Flavio

Batch task plugin logs

Balázs Fehér — Fri, 24 Apr 2026 13:06:58 GMT

Hi All,

I am implementing a batch task plugin and during batch task execution multiple error, warning or info event can happen. Errors of course block the execution, but warnings can be ignored, info item are just for informing the user know what happened. I am looking for the best way to display these events/messages for the user. Based on the UI there should definitely exists a possibility to do such thing (see image below). For errors I just need to throw an exception, but I do not see how can I add a warning. So my question is that, how can I add a "Warning" in a "AbstractFileContentProcessingAutomaticTask" specifically? And is there a way to add info messages?
Thank you in advance for your reply,
Balazs

Verification plugin triggered when confirming a segment even if disabled

Arturo Vazquez Rodriguez — Fri, 17 Apr 2026 09:07:28 GMT

Hello,

I have developed a custom verification plugin for Trados Studio.

When I disable it in the project settings, it won't be triggered when pressing F8, which is expected and completely normal.

The problem is that confirming a segment triggers the verifications performed by that plugin even if the plugin is completely disabled (that is, unchecked in the Verification options node).

I am using Trados Studio 2024 SR1 18.1.3.6657

I cannot share the source code publicly or the plugin, but I can privately, please get in touch with me for that.

Thanks!

Kind regards,

Arturo

MultiTerm COM API Termbases.New() fails when Croatian is present in XDT, but MultiTerm Desktop can create the termbase

Adam Csillag — Fri, 10 Apr 2026 11:16:49 GMT

Hello,

I’m seeing a reproducible issue with MultiTerm COM automation when creating a local termbase from an .xdt definition.

Environment

MultiTerm Desktop 2022 SR2 - 17.2.5.2838
Trados Studio 2022 SR2 - 17.2.12.19268
C# app running as x86 (Environment.Is64BitProcess = False)
Interop: Sdl.MultiTerm.TMO.Interop

Code

Sdl.MultiTerm.TMO.Interop.Application oMt = new Sdl.MultiTerm.TMO.Interop.Application();
TermbaseRepository oLocalRep = oMt.LocalRepository;
oLocalRep.Connect("", "");

Termbases oTbs = oLocalRep.Termbases;
oTbs.New(name, "", definition, sdltbPath);

Example values used

name = "Test"
definition = C:\Users\...\Temp\Test_20260409_141955534\Test.xdt
sdltbPath = C:\Users\...\Temp\Test_20260409_141955534\Test.sdltb

What I tested

The process is 32-bit (Environment.Is64BitProcess = False)
definition exists
sdltbPath does not exist before calling New(...)
Creating in %TEMP% gives the same result as other local paths
Opening an existing .sdltb through COM works:

oLocalRep.Termbases.Add(existingTbPath, "", "");
var tb = oLocalRep.Termbases[existingTbPath];

MultiTerm Desktop can successfully create the termbase from the same .xdt

Observed behavior

Termbases.New(...) throws:
- System.Runtime.InteropServices.COMException: 'MultiTerm is unable to create the termbase.'
After a lot of testing, I found that the problem is related to Croatian in the .xdt
If I remove Croatian from the termbase definition, Termbases.New(...) succeeds
If Croatian is present, Termbases.New(...) fails
However, MultiTerm Desktop is able to create the same termbase from the same .xdt

Question

Is this a known issue in the MultiTerm COM API with Croatian language handling during termbase creation?
Is there a specific Croatian language code/locale that COM expects here?
Could this be related to SH-HR vs hr-HR handling?

Since Desktop can create the termbase, but COM cannot when Croatian is included, this looks like an API-specific issue rather than a broken .xdt.

Thanks in advance for any guidance.

API calls to pretranslate files using DeepL plugin no longer work

TTS Team — Wed, 01 Apr 2026 14:25:52 GMT

Hello,

Since DeepL changed their authentication methods, we no longer can pretranslate our files using API calls to Trados 2024. It still work when pretranslating "manually" from within Trados Studio, but when using the API call

project.RunAutomaticTask(targetFiles.GetIds(), AutomaticTaskTemplateIds.PreTranslateFiles)

, it won't work.

We've narrowed it down to DeepL API key authentication: when adding the DeepL provider manually in Trados Studio, the API key is automatically authenticated when you enter it in the settings dialog for DeepL, but when our external tool uses Trados API to add the DeepL provider to the project using our API key, no such validation occurs, and that's what blocks the pretranslation task from working.

So my question is: is there any way to make it work, it worked just fine before the authentication change? We even tried duplicating the API key authentication when adding the provider to the project, but no luck there.

Thanks for any help on this subject.

Create Project Via API shows files as Reference

Mark Owens — Mon, 30 Mar 2026 11:05:15 GMT

I've recently upgraded to Trados 2024, and am running code that creates a new project from a Studio 2024 template, add files, and machine translates. All VS references are for Studio 2024 assemblies.

The template is setup exactly as you'd expect to do this. There is no memory selected, and the DeepL translation configuration is correct. The file types for the template have most entries in the list unticked, but XML2: MadCap Compliant is ticked.

The program steps are:

Create project
AddFolderWithFiles (recursively)
Save project
Scan files
Save project
ConvertToTranslatableFormat (via RunAutomatiobTask)
CopyToTargetLanguages (via RunAutomatiobTask)
Save project
Modify settings to applyAutomatedTranslation
Save settings
Save project
PreTranslateFiles (via RunAutomatiobTask)
Save project

It never seems to use the project template setting to recognise the .htm files are translatable.

If I create the project manually, with the same template, same source files, it performs the MT as expected.

There must be some sort of gotcha going on. Can anyone tell me where I'm going wrong?
Thanks

Mark

Request for meeting to clarify TM matching behavior with Lara integration

Giulia Ceccacci — Thu, 05 Mar 2026 09:18:45 GMT

My name is Giulia Ceccacci and I work at Translated, where I focus on technical support for Lara, our AI translation platform.

I've recently been running several tests on the integration between Lara and Trados Studio, and I’ve noticed a few behaviors regarding translation memory matching and segment confirmation that I would like to better understand from your side.

In particular, I’m seeing some inconsistencies in how TM matches (including 90% matches) are recognized by Trados depending on whether the TM is selected in Trados, in Lara, or in both. In some cases Lara correctly retrieves a match from the TM, but Trados does not recognize it as a TM match, which means the segment still needs to be manually confirmed.

Additionally, I’m observing a bug where the suggested translation reverts to the source language when the segment is confirmed, which we are currently investigating on our side.

Since some of these behaviors may depend on how Trados handles TM matches, pre-translation settings (e.g. Keep Existing Translations), and external providers, I think it would be very helpful to schedule a short meeting to walk through the scenarios together and clarify what we should expect from the Trados side.

Would you be available for a quick call in the coming days?

Let me know,

Giulia

TradosAPI within Plunet Ran out of Memory message

David McDermit — Tue, 03 Mar 2026 14:54:35 GMT

Hello

Have been having an issue with the TradosAPI within Plunet to run analysis of translation requests.

Presently have updated the server and all programs within Plunet and the TradosAPI. This seems to have fixed the Critical error message we would get when running jobs over 1100 words. After getting everything up-to-date we are now running into a Ran out of Memory message when running larger jobs.

What can I supply that might help solve this issue?

GroupShare: Adding Translation Units directly via Trados API always results in Discard – expected behaviour?

Damien Morard — Mon, 09 Feb 2026 15:43:36 GMT

Hello everyone,

I’m currently experimenting with the Trados APIs to programmatically populate a server-based GroupShare TM (GS 2020 / Studio 2021), and I’ve run into a behaviour that I’d like to better understand or confirm.

Context

GroupShare 2020
Trados Studio 2021
Server-based TM created specifically for testing
User has admin roles in GroupShare
Importing a TMX manually via Studio works
Importing a TMX programmatically via the API also works

However, when trying to add Translation Units directly via the API, nothing is persisted.

What I’m trying to do

I’m using ServerBasedTranslationMemoryLanguageDirection.AddTranslationUnit(...) to insert a simple TU (plain text, no tags).

Below is a simplified example of the code I’m using.
(It does not contain all variables/constants, but should give a clear idea of the approach.)

private static void Main()
{
try
{
AssemblyResolver.Resolve();

  var server = new TranslationProviderServer(
   new Uri(GROUPSHARE_TM_ENDPOINT),
   useWindowsAuthentication: true,
   userName: null,
   password: null);

var tms = server.GetTranslationMemories(TranslationMemoryProperties.None).ToList();
Console.WriteLine($"Connection OK. Found {tms.Count} TM(s) on the server:");

  foreach (var t in tms)
  {
   Console.WriteLine($"- {t.Name} | {t.Id}");
  }

var tmRef = tms.FirstOrDefault(t =>
string.Equals(t.Name, TM_NAME, StringComparison.OrdinalIgnoreCase));

  if (tmRef == null)
  {
   return;
  }

  var tm = server.GetTranslationMemory(tmRef.Id, TranslationMemoryProperties.None);
  if (tm == null)
  {
   return;
  }

var sourceCulture = new CultureInfo("en-GB");
var targetCulture = new CultureInfo("fr-FR");

  var ld = tm.LanguageDirections.GetLanguageDirection("en-GB", "fr-FR");
  if (ld == null)
  {
   return;
  }

  var tu = new TranslationUnit
  {
   SourceSegment = BuildPlainTextSegment(sourceCulture, "Hello world!"),
   TargetSegment = BuildPlainTextSegment(targetCulture, "Bonjour le monde !")
  };

var importSettings = new ImportSettings();
var result = ld.AddTranslationUnit(tu, importSettings);

  Console.WriteLine($"Cached TU count: {tm.CachedTranslationUnitCount}");
  Console.WriteLine($"Actual TU count: {tm.GetTranslationUnitCount()}");
  Console.WriteLine($"TM IsReadOnly: {tm.IsReadOnly}");
  Console.WriteLine($"TM SupportsUpdate: {tm.SupportsUpdate}");
  Console.WriteLine($"Has Delete permission: {tm.HasPermission(TranslationMemoryPermissions.Delete)}");
Console.WriteLine($"Has Add permission: {tm.HasPermission(TranslationMemoryPermissions.Add)}");
Console.WriteLine($"Has Edit permission: {tm.HasPermission(TranslationMemoryPermissions.Edit)}");
Console.WriteLine($"ImportResult: {result}");
}
catch (Exception ex)
{
Console.WriteLine("Error while inserting TU:");
Console.WriteLine(ex);
}
}

private static Segment BuildPlainTextSegment(CultureInfo culture, string text)
{
var segment = new Segment(culture);
segment.Add(new SdlText(text));
return segment;
}

Output

After running this code, I consistently get the following output:

Cached TU count: 0
Actual TU count: 0
TM IsReadOnly: False
TM SupportsUpdate: True
Has Delete permission: True
Has Add permission: True
Has Edit permission: True
ImportResult: Discard-(0, xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)-OK

So:

No exception is thrown
Permissions look fine
The TM is writable
But no TU is added
ImportResult always comes back as Discard

Additional observation / question

When switching to a TMX-based approach (i.e. generating a TMX file and importing it via the API), the import works correctly and the TUs are effectively added to the server-based TM.
In contrast, inserting TUs one by one via AddTranslationUnit consistently results in a Discard without any explicit error, even when using an admin account.
This makes me wonder whether direct TU insertion via the API is intentionally restricted in GroupShare, or if there is some server-side policy or design decision that silently discards such inserts.

Is this behaviour expected for server-based GroupShare TMs, and is the recommended or supported approach to populate them exclusively via batch TMX imports rather than direct TU insertion?

Thanks in advance!

Damien

Trados API Extraction Failure: File Version Could Not Be Identified: New Case Comment

Dpto. Tecnico Linguaserve — Mon, 02 Feb 2026 12:22:46 GMT

Hello:

We are launching a process from the Trados API to read the contents of an SDLXLIFF file, and it is returning an error that we are unable to identify:

Error while extracting data from 8950d65b-9b65-4160-9389-410ee8109862: An error occurred while trying to determine the file version.
at Sdl.ProjectAutomation.FileBased.FileBasedProject..ctor(String projectFilePath)
at ApiTAO.Tasks.FileExtractionData.FileExtractionDataTask.ExtractData(String projectPath, String fileId)

We are unable to determine the cause of the error because, apparently, everything in the SDLXLIFF file looks correct.

How can we get more information about the possible issue? Could you help us?

There is an event (SegmentsConfirmationLevelChanged) that is triggered for a single segment. Is there an equivalent event that is triggered once for multiple segments after a multi-selection?

Usman Asif — Wed, 17 Dec 2025 19:37:54 GMT

There is an event called SegmentsConfirmationLevelChanged that is triggered when the confirmation level of a segment changes. However, when multiple segments are selected and their status is changed in bulk, this event is fired separately for each individual segment. There does not appear to be a single event that represents the completion of the bulk action. Because of this, it is difficult to determine when all selected segments have finished updating. Is there an equivalent document-level or bulk event that is triggered once after the confirmation level is changed for multiple selected segments?

Scan batch task on Trados API randomly fails with message "The file exists."

Stelios Mathioulakis — Wed, 26 Nov 2025 11:21:47 GMT

Hello,

I have a typical function to add files to a project. I have a very large catalog of html files that I need to convert, around 70k files. I have set up multiple Python workers for this task and they invoke the C# code with the relevant parameters like source, target lang, output path, input file path. However, this typical code here randomly fails:

private void AddFiles(FileBasedProject project, string sourceFilePath)
{
// AddFiles expects an array of strings
string[] sourceFilePaths = { sourceFilePath };
project.AddFiles(sourceFilePaths);

ProjectFile[] projectFiles = project.GetSourceLanguageFiles();

AutomaticTask scan = project.RunAutomaticTask(projectFiles.GetIds(), AutomaticTaskTemplateIds.Scan);

}

the problem is that the scan object has the message "The file exists.". This Add files function sits here in a typical sequence of calls for Trados automation:

newProject = new FileBasedProject(this.GetProjectInfo(srcLocale, trgLocale, outputpath));
var settings_ = newProject.GetSettings();
var xliffSettings = settings_.GetSettingsGroup("SDL XLIFF 1.0 v 1.0.0.0");
xliffSettings.GetSetting<bool>("ValidateXliff").Value = false;
newProject.UpdateSettings(settings_);

this.AddFiles(newProject, sourceFilePath);

What does this "The file exists." even mean? Can you see where this could come from?

If I shut the process off and then try only a failed task on its own, then it works. Can someone help me on this? I have never encountered this before. I am using Trados 2022.

" HRESULT E_FAIL-Error" during deletion of entries in a MultiTerm termbase

Nils Jörn — Fri, 14 Nov 2025 10:43:15 GMT

Dear all,

I'm creating a little command line tool with Visual Basic which shall delete all entries from a MultiTerm termbase which has about 4000 entries.
I'm using MultiTerm 18.1.2.3594 and have set a reference to "C:\Program Files (x86)\Common Files\Trados\MultiTerm18\Sdl.MultiTerm.TMO.dll".

Im using the following for... next loop:

For entryCount = 1 To oTb.Entries.Count
    Console.WriteLine($"EntryCount: {entryCount}")
    If oTb IsNot Nothing Then
        If oTb.Entries IsNot Nothing Then
            oTb.Entries.Item(oTb.Entries.GetEntryIDs(entryCount)).Delete()
        End If
    End If
Next

Unfortunately, runnnig that loop leads to the following error message after running some time and deleting entries as expected.

"An HRESULT E_FAIL error was returned when calling a COM component.
StackTrace: at MultiTermIX.IEntryIDs.get_Item(Int32 Index)
at MultiTerm_BatchImportExport.DatabaseImportExport._Closure$__6-0._Lambda$__1() in C:\tmp\MultiTerm-BatchImportExport.vb:Line 168."

What I'm really wondering about is, that the error is gone, if I'm exchanging the context of line 168, which is "oTb.Entries.Item(oTb.Entries.GetEntryIDs(entryCount)).Delete()", by "Console.WriteLine($"Content: {oTb.Entries.Item(oTb.Entries.GetEntryIDs(entryCount)).Content.Content}")".

I don't have any clue, why deleting the entries leads to that error, but listing the context of each entry does not.

Please be so kind to let me know, what I'm doing wrong.
Any help and even a hint, pointing me in the right direction is very much appreciated.

If you have any further question or if you need any further information, please don't hesitate to let me know.

Best regards and have a nice day.
Nils
