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

    Hi, same problem here with same error. Trados does not open at all.

    Please follow the instructions given by  

    If these (especially the help article 1414) do not help, go to C:\Users\Your_susername\AppData\Roaming\Trados\Trados Studio\17 and delete the subfolder Plugins there.

    Thank you J. Czopik, did you update your Trados? is it working?
  • 0 in reply to Eli Levi

    Yes, I did. However, my installation did include only recent plugins and was up-to-date. The error message above seems to be connected to a cloud.A Studio reset as described in the article quoted by Ali should work.
  • 0 in reply to Alison Field

    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???

    Oh I was to quick saying I managed to get Studio working again. After restart error comes back....

    It absurd...

    I tried all suggestions provided by  and . Additionally, I disabled Onedrive and my Antivirus software entirely.
    Yet, the same error pops up after launching Trados, and then Trados fails to load after hitting the "OK" button.
    It seems like there might be a more serious issue with this update.
    Tagging        for awareness.
    Is there an updated guide (for 2023) on downgrading Trados safely without losing cloud and local projects?
    I have attached my latest stack trace below:
