Hi Cylvie Frechette , sorry to hear you're having issues with starting studio.

Possible Cause:

This error typically occurs due to corrupted user settings or configuration files within Trados Studio. Resetting these files often resolves the issue.

Here are some options you can follow to fix the problem

let me know how it goes.

Option 1: Reset Trados Studio to Default Settings

Step 1: Close Trados Studio

• Ensure that SDL Trados Studio is completely closed before proceeding.

Step 2: Rename the Settings Folder

Navigate to the Settings Folder:

• Press `Windows Key + R` to open the Run dialog.
• Type `%appdata%\SDL\SDL Trados Studio\Studio16` and press `Enter`.

Rename the Folder:

• Find the file named `UserSettings.xml` and rename it to `UserSettings_old.xml`.
• Alternatively, you can rename the entire `Studio16` folder to `Studio16_old`.

Step 3: Restart Trados Studio

• Launch SDL Trados Studio.
• The application will create a new settings folder with default values.
• Check if the application starts without the error.

Option 2: Delete the FilesView Configuration File

Step 1: Close Trados Studio

• Make sure SDL Trados Studio is not running.

Step 2: Navigate to the Local App Data Folder

• Press `Windows Key + R` to open the Run dialog.
• Type `%localappdata%\SDL\SDL Trados Studio\Studio16` and press `Enter`.

Step 3: Delete the Layout Configuration Files

• Look for files related to layout and views, such as `BaseSettings.xml`, `Plugincache.xml`, or specifically any file that references `FilesView`.
• Caution: Deleting these files will reset your layout customizations.

Step 4: Restart Trados Studio

• Open SDL Trados Studio to see if the issue is resolved.

Option 3: Repair or Reinstall Trados Studio

Step 1: Repair Installation

• Access Programs and Features:
• Go to `Control Panel` > `Programs` > `Programs and Features`.
• Find SDL Trados Studio 2021 SR2:
• Scroll through the list and locate `SDL Trados Studio 2021 SR2`.
• Repair the Installation:
• Right-click on it and select `Repair`.
• Follow the on-screen instructions to complete the repair process.

Step 2: Restart Your Computer

• After the repair is complete, restart your computer.

Step 3: Launch Trados Studio

• Open the application to see if the issue has been resolved.

Option 4: Check for Conflicting Plugins or Add-ons

Sometimes, third-party plugins or add-ons can cause conflicts.

Step 1: Close Trados Studio

• Make sure SDL Trados Studio is not running.

Step 2: Disable Plugins

• Navigate to the Trados Studio plugins folder:
•  `%appdata%\SDL\SDL Trados Studio\16\Plugins`
• Temporarily move any third-party plugin files to another location.

Step 3: Restart Trados Studio

• Launch the application to test if the error persists.

Hello Patrick,

Apologies for the late response, but the show must go on over here. I actually forgot to mention, that I am using Trados Studio on a Mac running Windows 11 on a virtual machine, so there is no Windows key on the keyboard. I was only able to try Option 3, which did not work. For other options, I have not been able able to locate the files you mention. Would mind give the full file paths?

You do not need to have a Windows key. You should have the search option in your Windows. Please copy and paste this there: C:\Users\%USERNAME%\AppData\Roaming\SDL\SDL Trados Studio\

Then rename both the folder 16 to _16 and Studio16 to _Studio16.

This should help.

Thank you Jerzy for providing the full path. I was able to try options 1 and 2. Option 2 is the one that did the trick. But after that, changing to my user own profile caused the issue again, so I had to recreate all my customized shortcuts and so on from the default profile. At least, deleting (or renaming) these files allowed me to launch the application, which is the most critical thing.

Thank you for your help.

So it seems your user profile is damaged. As you recreated what was needed in the profile, export it to a backup folder for future use. This way you will be able to restore the profile in case it gets damaged.

To do so, go to File -> Setup -> Manage user profiles and chose the export option. Save the exported profile in an easy to find folder.

Thank you for this tip, Jerzy. I think the issue started when I started working with both Studio 2024 and Studio 2021. Somehow a profile created in one version of Studio could not be used or got damages when trying to use it with the other version. I don't remember which version and what exactly were the circumstances when the issue arose, but I suspect it has to do with version incompatibilities in terms of user profiles.  Now I am running both versions of Studio with different user profiles, trying to emulate manually the one that works in Studio 2024 back into Studio 2021.
