Thanks. I might have to look into a virtual PC sometime. I've been using Acronis to clone my hard drive, but hadn't used it yet on the new computer. I built the computer on Friday evening, loaded Windows 7 on Saturday, and finally had the chance to load software on Sunday.
I bought Windows 7 Professional 64-bit since I was told that it could run older software and I had something I wanted to keep using. When I installed Research Assistant and Sunbird (Mozilla calendar), the Program Compatibility Assistant opened and asked if I wanted to re-install the program...
