said.......If you want the XP version to run on Windows 7, then what you need to do is to copy the "Freecell.exe" and "Cards.dll" files from the C:\Windows\System32 folder on your XP system to some other folder on your Windows 7 system. Put both files in the same folder, but don't put them into the System32 folder 'cause they'll wipe out the Windows 7 version of the program.
To run the program, just double-click the "Freecell.exe" file. You can create a shortcut to the file on your desktop or pin the program to the taskbar or start menu.
