      Hello jekweji001, 

      Can you please try installing a clean setup and let me know

      Steps:

      1. Uninstall the Ansys package as an administrator.
      2. Rename ‘ %temp%\.ansys’ to ‘‘ %temp%\.ansys.old’
      3. Rename ‘AppData\Roaming\Ansys’ to ‘AppData\Roaming\Ansys.old’
      4. Rename ‘Documents\Ansoft’ to ‘Documents\Ansoft.old’, if any
      5. Delete 'C:\Program Files\ANSYS Inc' 
      6. Reinstall the required Ansys package as an administrator.

      I hope it helps.

      Wishes, 

      Mrunali.
