As the subject line implies, there is an issue with that App (already experienced earlier with Studio 2019). My computer has the now unsupported WIN 7 Home Professional, I admit, but due to lack of time (despite Corona situation here) I couldn't upgrade the O/S yet. The App should work under this O/S nevertheless. My current version of the CAT is SDL Trados Studio 2021 SR1 - 16.1.3.4096.
I downloaded the latest version of that App, but there was an error message that look very similar to that one I experienced using Studio 2019 SR2. So I uninstalled this App again und used CCleaner tjhereafter.
Can anybody help me to find a solution to use this App as intended?
