You will need to be more specific with which remote you speak. Because .CCP itself NEVER had a problem running on any of the Windows versions. Not that I ever remember.
But certain remotes (MX980, MX6000, etc.) had problems with versions of Windows, because URC was stupid and used extra software modules by Microsoft, etc. for those specific remotes. Stuff that even a half-wit should have known would cause issues, not long down the road. But hey, that's the upper personnel that have been steering URC now for almost 2 decades.
