incomplete plugin uninstall

Nadège de Neef — Mon, 16 Mar 2026 13:54:27 GMT

For a schoolproject I tried to install 2 plugins into Trados. Trados then told me to close the app and restart it. When I did this I got an error, saying Trados couldn't open. I tried to uninstall Trados and install it again but that didn't help. I also tried to remove some plugin-files from my discoverer but I'm not so good with the technical side of these things.

Now I get the following message:

When I close it and open it again I still get that notification. What can I do to make my Trados operational again? Since I need this for class in 2 days.

[Trados 2024 SR1] Installation error

Jaroslava Nela Sodomková — Mon, 27 Oct 2025 16:25:29 GMT

Hello. I tried to install Trados 2024 SR1, but the installation process does not advance beyond this screen:

I have already installed the most recent version of Microsoft Visual C++, so that should not be an issue.

Here is the debug log:

Cannot access my account

Océane Sannier — Mon, 12 May 2025 08:50:45 GMT

Hello, I'm a university student, I cannot access to my account anymore. It says that my account isn't linK to any cloud account. My teacher tried several times to delete and add me, sending me several invitations, but each time, it said that the invitation was meant to someone else. We contacted someone from RWS and we tried different solutons but none of them worked.

Please provide advice.

Thank you

Trados Error: "The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters."

Jenny Nguyen — Wed, 02 Apr 2025 01:52:32 GMT

I am currently a student using SDL Trados Studio 2024 - 18.0.0.1013. It is provided by my school, Houston Community College, which is an academic partner of Trados.

Last Sunday, I turned on my computer and received an error message from Trados saying that the Base-64 string is not valid. This is the first time I have ever received this type of message. I looked and read the Knowledge Base and Community sites that similarly mentioned about this issue. I have tried different ways to get rid of the error message, such as renaming certain files, restarting my computer, uninstalling and reinstalling Trados, and repairing it. Unfortunately, none of these suggestions were successful.

Therefore, I am asking in this forum for help from experts by opening a case to solve this issue. I have lost 2 days ever since the message occurred. Please help me solve this issue as soon as possible.

It doesn't matter, it matters that you rename it.

Hi Elisa,

I have looked at this link, but I am not sure what to rename the file into. It just says to rename the file.

RE: Request for Resources to Localize the Trados Homepage into Arabic for Academic Project

The Trados homepage is public, so of course you can take this and translate it for your project as long as you won't be republishing it anywhere else other than to demonstrate the success at the end.

You could use a tool like https://www.httrack.com/ to download all the files you probably need, or if you want to be more specific use the developer tools in Chrome to pick out what you think you need.

I would mirror what's there. All the Trados branding is the same in any language.

Since this is a public website, and since this will be an academic project that will not be published in public I think you should feel free to use whatever you are allowed to use.

If you have more specific questions please feel free to ask.

Request for Resources to Localize the Trados Homepage into Arabic for Academic Project

ameer nizar — Mon, 30 Dec 2024 14:22:10 GMT

My name is Ameer Nizar, and I am a student at Middle East University (Jordan). I am currently working on an academic project to localize the official Trados homepage into Arabic. This involves translating all visible elements (text, dropdowns, functionalities) and recreating the design while preserving Trados' branding, colors, and visuals.

I am reaching out to the community for guidance and assistance in obtaining the necessary resources for this project, such as:

1. Access to the homepage’s source files or design resources.

2. Any guidelines related to Trados’ branding and functionality preferences.

3. Permission to use AI tools or other resources to help with recreating the homepage design.

This project is purely academic, and I would be happy to share the localized version with Trados if it could be of use to your organization. I greatly appreciate any advice, resources, or directions that could help me complete this project.

Thank you for your time and consideration!

Best regards,

Ameer Nizar Abd Al Latif

Frozen, bugged-ridden error messages

Maria Quintana — Sun, 22 Dec 2024 03:45:14 GMT

I am a college student working on my school Microsoft Remote Desk. Trados has been super sluggish lately, and I cannot change or repair it, among most of other

troubleshooting options, because I do not have the privileges to do so. I deleted temporary files, created TMs and projects over and over, restarted the program and the

computer countless time. I still cannot pass all sorts of error messages every time I try to open the Editor view or click of other functions whose result is to freeze. What else

can I do aside from informing my teacher that I am stuck with the assignments?

RE: Frozen, bugged-ridden error messages

Maria Quintana — Tue, 24 Dec 2024 20:15:53 GMT

You are right, Paul There is nothing else I can do unless the school does. I emailed the department director and the teachers about taking action on issues of this sort and just forwarded your email to them. Let´s see how the situation plays out.

However, I tried to download a 30-day trial period with two different email accounts in hopes of finishing my homework, but,

although I downloaded it successfully on my Mac, the trial did not open (You cannot open this application). I wonder if this happened because I downloaded the program on the Remote Desk environment, thinking naively I would open it where I have all my files and folders saved...

Thanks so much for your time and dedication. Happy Holidays!

ok - that would explain a few things. I'll contact your University and see if we can help because they have been provided with Trados Studio 2024 and Trados Team. This would allow a few things:

you can work entirely in a browser and not install Trados Studio at all. Can make things a lot simpler.
you can download and install Trados Studio on any computer you like and licence it from Trados Team. This puts everything in your own control.

If you're still using Trados Studio 2022 then I think this is most likely because your admins have not understood, or not got around to making use of the latest versions of the software. We provided Trados Team from Trados Studio 2022 onwards for Universities to be able to manage their courses more efficiently and also so they always had access to the latest software we provide. It's free, so the only barrier to using it is the University itself.
