I am not able to close myTrados Studio Freelance because I get the error message "Could not load file or assembly 'idrsnet15.dll' or one of its dependencies". Please advice.

I just reinstalled Trados Studio 2021 SR2, upgraded to the .12 version and installed the plugins (including IRIS). When I got a warning message, that IRIS might cause problems, I unistalled it again. 

Now I cannot shut down my SDL Trados Studio application. 

I get the error message above. 

Any help would be greatly appreciated. 

I haven't even tried to work with any PDF files yet.

    Question improvement suggestion: Please provide the exact version of Trados Studio you are using, as well as any specific troubleshooting steps you have already attempted.  

    In the meantime, based on the information you have provided, here is a suggested answer to your question:  

    Hello,  

    It seems you're encountering an issue with closing Trados Studio due to the error message regarding 'idrsnet15.dll'. Here are some steps you can follow to troubleshoot and potentially resolve this issue:

    **Step 1:** Close Trados Studio completely. If it does not close normally, you may need to use the Task Manager (Ctrl + Shift + Esc) to end the process.

    **Step 2:** Ensure that you have the necessary dependencies installed. Since you mentioned the error relates to 'idrsnet15.dll', it may be beneficial to install the Microsoft Visual C++ 2010 Redistributable (x86). You can download it from the official Microsoft website.

    **Step 3:** Navigate to the following directory:  

    `C:\Users\%username%\AppData\Roaming\SDL\SDL Trados Studio\16`  

    If you can't find the path, ensure that hidden items are visible in Windows File Explorer by clicking on the "View" tab and checking the "Hidden items" checkbox.

    **Step 4:** Rename the `Plugins` folder to `Plugins_old`. This will disable any third-party plugins that might be causing the issue.

    **Step 5:** Optionally, you can run a repair installation of Trados Studio. To do this, go to Control Panel > Programs and Features, find Trados Studio, right-click on it, and select "Repair".

    **Step 6:** Restart your computer and then try to open Trados Studio again.

    If the issue persists, consider checking for any antivirus software that could be interfering with the application. Adding the Trados Studio installation folder as an exception in your antivirus settings can sometimes resolve such issues.

    If none of these steps work, please consider reinstalling Trados Studio as a last resort, ensuring you back up your settings, projects, and translation memories first.

  • Hi 

    Please check the article about uninstalling an app and follow the troubleshooting that removes the plugin manually (follow the path where the plugin information is stored) and rename the files indicated there in Solution 2:

    https://gateway.rws.com/csm?sys_kb_id=2402cf1083d42ed4a6b1fab8beaad3c0&id=kb_article_view&sysparm_rank=1&sysparm_tsqueryId=3298d4f483bf325415c56180deaad3c7

    You can also do a reset of Trados to default if the issue persists:

    And let me know if the above solutions solved the issue.

    Best regards,
