Installation problem -mistakenly identifying OS as 64bit XP

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?



Hi Dan,

You’ve got one of the early Rhino 5 DVDs, and there’s a bug in those first DVDs that caused this problem. To fix it, please download the latest Rhino 5 from

Thanks Brian, I am downloading now.
