Hello Michael,
Can you try the following:
Make sure no Ansys programs are running
Go to : %APPDATA%\ (This will take you to a directory: C:\Users\\AppData\Roaming\)
You should see a directory named: Ansys, rename that directory to: Ansys.old
Now try to run and let me know if this doesn't help.
Regards,
Nanda.
