The Blackhawk Codes on Disk and other programs will run great on Windows XP and old Windows computers. Newer Vista and Win 7 32 bit will usually run, but you may need to try and run the program multiple times before it loads. The Professional version of Win 7 seems to work much better. 64 bit Win 7 home edition doesn't seem to be working at this time.
