Generals will not run after switching to X2
This is not much of a how-to but rather an important note. When upgrading from a single core to a dual core processor several games, especial Command and Conquer: Generals and games based on the same game engine such as Battle for Middle Earth may not run correctly if at all. After a lengthy search no standard solution was found other than to reinstall windows and the games. This ensures that they are installed and configured correctly for your hardware.
When conducting such a large hardware upgrade like single core to dual core, at least with an operating system not designed with an era of single-to-dual-core upgrades in mind, it is probably safe to assume that you should always do a clean install.
C&C Generals need to be reinstalled please refer to this website http://planetcnc.gamespy.com/View.php?view=FAQ.Detail&id=6
and read about issues when changing the hardware.
Thanks and enjoy playing Generals Zero Hour
My computers first boot ever was with dual core. And it still wont work because of it.
