Yeah, stuff like that continues to be the best use-case for windows virtualization. Sounds a lot like trying to upgrade the BIOS or Firmware on an older PC; often the installer is some binary that only runs on Windows of the same vintage.
Backwards-compatibility with older web browsers so engineers can build websites for them, is another. I’ve also heard of industrial automation (e.g. CNC machines) being married to Win2k or WinXP, so being able to run an old OS on new hardware is crucial.






Or you’d get lucky and some other program you installed happens to have the right dependencies. Just copy them to the application install dir or to
C:\windows\win32\and off you go.
