will this game play on wind 7 in the ex mode ?
The ex mode?
Do you mean XP mode?
XP mode is essentially the same as Virtual PC with a Windows XP VM, made to look more "integrated" with Windows 7 than regular Virtual PC.
You would need Windows 7 Pro or Ultimate (or Enterprise) to use XP Mode.
You can't use XP mode for Windows 7 Home.
If you're going to use Virtual PC for this game, you're probably better off installing Windows 98 or ME inside it rather than XP.
