hmmm...I'm not sure it will work. Check out the Windows 7 Compatibility Center for more information - http://www.microsoft.com/windows/compatibility/windows-7/en-us/Details.aspx?type=Software&p=Myst%20IV%3a%20Revelation&v=Ubisoft&uid=&l=en&pf=0&pi=0&s=myst&os=64-bit
Since you already have a Windows 7 laptop and the game, you can give it a try. If you have Windows 7 Professional or Ultimate, you can try playing the game in XP Mode...
Let us know what happens!
