I have not installed Vista beta yet, due to the fact that Halo PC(a game I\nlove playing) is apparently incompatible with Vista. A friend of mine was\nunable to install Halo on his copy of Vista. When the install is attempted,\nit says that Halo PC will not run without DirectX 9. Apparently it isn't\nforward compatible - an odd problem. Is there a way around this problem\nwithout doing a dual boot?\n\nThanks for any help!
