Hi again Sorin,

I tried the other solution too, 

• for Trados Studio 2015-2021: C:\Users\%USERNAME%\AppData\Roaming\SDL\Platform\Identity\SDLTradosStudio.exe and rename the folder SdlIdentityCredentials into SdlIdentityCredentials_old.

and here I get to rename the folder successfully, but upon starting Trados Studio 2022 I still get the "Failed to add window command bar extensions." error.

Please help because I have impending deadlines today.

Hello Paola Bortolotti 

Ok, then please try to rename the "17" folder (while Studio is closed) from: C:\Users\%Username%\AppData\Roaming\Trados\Trados Studio

Thank you,

Sorin

I have renamed the "17" folder to "RENAMED 18" but Studio will not start and displays the same "Failed...extensions." error message.
