We've got an app used by CNC workers called Cimatron by 3D Systems. I tried doing an upgrade from version E11 to E13 and get this error:

The Application log shows this:

I've tried reinstalling, a full uninstall and then reinstall. Even rolled back to a Restore Point to before E13 was installed. No change.
Any ideas on what I can try or look at?
