Just to rule out the possibility please can you ask them to try installing each of the items under C:Program FilesANSYS Incv221prereq to ensure they have the right prerequisites in place, I see an message shown below:
The installation will copy the prerequisite setup files from the media in case you need to reconfigure later or if you need to configure client machines for products installed to a network share.
This may take a while ...
If they still face the issue, we can have a meeting to discuss. I will share these with the installation team, before having a meeting with you so that it will be easier to resolve the issue.
Regards.
