I have this same problem for premier 2021. I see the extracted files in the TEMP folder but nothing happens when i try to run them. Can someone explain the variable issue again that I can understand?
EDIT: I GOT IT TO WORK!!!
Yes, I created a new temp file at c:\TEMP and then made the environment changes suggested above. My son who downloads various program languages for coding, etc. said lately that exe files have not been running lately. He is trying to code a LIDAR at the moment. He has been downloading various java versions to work with an older version of the lidar code library due to compatibility issues. I vaguely recall that him saying that he changed some variables so the latest java version wouldn't run. I'll pester him tomorrow morning. Anyway, the fix above worked.
