Did you try using Windows XP Mode? XP Mode is free and is designed to run on Windows 7. You don't need an XP disk.
I used it on my first Win 7 machine. It worked perfectly and allowed me to run any of my older programs (like CFS2) in XP. Eventually I realized Win 7 was everything XP was and more so I didn't bother to install it on my next PC. If you have an old program that ran great on XP but not on Win 7 then XP Mode is the way to go. You do need to be running Windows 7 Professional, Enterprise, or Ultimate[FONT=WOL_Bold]to install it.[/FONT]
Here's a link to the Windows site explaining it and leading to the download page: http://windows.microsoft.com/en-us/windows7/install-and-use-windows-xp-mode-in-windows-7
Thanks Cody. I have Windows 7 Home, so it will not run in XP mode. Years ago, I made a virtual Xp machine on mine, but something in the rules must have changed I guess. When I did it the first time, I did not have to have a XP disk to install, now I do.
