I have a laptop that I was going to install Rhino 5 on for one of my guys. His system was originally XP 32-bit, but he upgraded to Win 7 32-bit. When I attempt to install Rhino, I received a warning that the computer was 64bit XP and that it is not a supported OS. This is wrong. How do I proceed? Is there a file that the Rhino installer is reading that could be updated?
