I had a typo:
DISM /Online /Cleanup-Image /RestoreHealth
===========
Please try to rename the APPDATA v241 folder once more:
Open a File Explorer.
In the address bar, enter %APPDATA%
Press Enter.
Open the Ansys folder
Rename v241 to v241.old
===========
None of the error codes are familar.
We normally don’t recommed uninstall / reinstall, but sometimes the Zip download files do not extract properly.
I prefer to download the ISO files, then mount each and run Setup.exe directly from the forst mounted DVD drive letter.
Hint: The first “disk” is the one with 241-1.dvd, second is 241-2.dvd, and so on
