STAAD 20.07.11.90 version not running

Hello,

I have STAAD.Pro version 20.07.11.90 and I get the following error when opening STAAD:

I get this error from either opening STAAD independently and looking for the file through STAAD or from double clicking the file from my machine.

My work IT was not able to fix this old version and instead successfully installed the latest version (22.08.00.175). Any chance to get the old version of STAAD to work as well? I'd like to use both.

Thank you.
