However, with that said, it may be possible to utilize Windows XP Mode and Windows Virtual PC just as COLGeek mentioned. Windows XP Mode and Windows Virtual PC, available on Windows 7 Professional and Windows 7 Ultimate, allow you to run multiple Windows environments, such as Windows XP Mode, from your Windows 7 desktop. For those who do are not currently running Windows 7 Professional, Windows 7 Enterprise, or Windows 7 Ultimate, there is an easy upgrade path to Windows 7 Professional or Windows 7 Ultimate through the Windows Anytime Upgrade program.
Please note that Windows XP Mode is a virtualized environment and is not recommended for graphically intense applications. However, the American Greetings Creatacard Platinum application should work just fine within such an environment.
