Trados 2022 suddenly stopped working properly today.  I was unable to open a file. I tried to uninstall Trados 2022 to solve the problem, but I could not finish the procedure. (I was able to do these things with Trados 2019 on the same desktop.)

I got a tecnical support for 2 hours and did the procedures the support staff provided, but I was not able to uninstall Trados 2022. So, I was instructed to post the problem in this community.

Problemes I encounted:

(1) When opening the file, the error message below appeared: "Unexpected exception when initializing view part フラグメント一致（fragment match)".

(2) When uninstalling, the error message below appeared :"Setup did not complete. The error is : Setup has detected a different version of this product already installed. If you still wish to remove or repair that version, you must use that version's isntaller."

[The recomennded procedure I took to solve the problems]

Unfortunately, the problem was not solved.

I would appreciate any help, as I even can neither uninstall nor use Trados 2022.
