Your specifications probably blew up it's head.
Yeah, you won't be able to get it to work for awhile. And if you're thinking you'll get a patch for Generals: HA! The only reason they even patched Zero Hour 2 years ago was because everyone over at the Battle For Middle Earth forums wouldn't shut up about how Zero Hour still hasn't been patched, and they wouldn't buy BFME until it was. There will be no compatibility patch from EA, so you'll have to hope for a backwards compatibility patch from Microsoft.
