Trados studio stopped working right after installing Cumulative Update 7 (Build 17.1.7.17560) - Object reference not set to an instance of an object

Arya. H

Hi, 

I recently installed Cumulative Update 7 for Trados Studio 2022 SR1 (Build 17.1.7.17560).
Before this, I was using the latest version, which was Cumulative Update 6 Trados Studio 2022 SR1.
However, I am now encountering this infamous error message that appears as soon as I open Studio:
Object reference not set to an instance of an object

After clicking OK, Trados Studio shuts down completely

Attached are the XML file (error details).

I would greatly appreciate any suggestions you may have to solve this issue.

    Hi  

    I'm sure someone at RWS will be able to help but in the meantime, try this:

    When a problem occurs after an update, the first thing to try is a Windows Repair of Studio (and/or MultiTerm components depending on what the problem is). This will repair software connections by e.g. checking for and replacing anything that is missing from the setup.

    Here is how:

    1. Close all SDL applications.
    2. Open the Control Panel:
      • Windows Vista/7: Start > Control Panel > Programs > Programs and Features.
      • Windows 8: Right-click on the screen at bottom-left corner and choose Control Panel > Uninstall a Program.
      • Windows 10: Right-click on Start > Control Panel > Select View by: Small Icons > Programs and Features
      • - or type 'Control Panel' in the search line on your bottom Windows toolbar.
    3. Click/highlight the relevant SDL product from the list (e.g. SDL Trados Studio 2021 etc) and click 'Uninstall/Change' either on the top toolbar or on the right-click dropdown menu (or just 'Repair' for MultiTerm), then select > Yes > Repair. Allow it to run. This will take longer for Studio than for the 3 main components of MultiTerm. Do NOT repair 'Remove suite of products' entries. These are only for uninstalling.
    4. Restart Studio/MultiTerm.

    There are further options here:

    Repairing your installation of Trados Studio

    Repairing your installation of MultiTerm Desktop

    If none of this helps, reply to that effect and someone from RWS can take a look at your setup remotely to solve the problem.

    All the best,

    Ali Slight smile

    I just did mention update and got the same error. I managed to get Studio 22 work again by changing file names mentioned in the other article but I dont have acces to my cloud projects either from studio nor from on my account directly!

    Very urgent!!! I got deadlines and I lost all my files in the middle of work!!!!

    Can You explain, why You publish updates that ruin working of an application???
