I have Chief Architect version 7 (dongle version) running but within XP 32 on a separate hard drive. As Ben has said, it is not compatible with Windows 7 or 8. It runs reasonably well in XP 32.

Yeah, I've been running it for years on XP successfully. I really wanted to get everything moved over to Win7 Pro. I wonder if the dongle would work under Win7 32bit? Thanks.
