I have recently purchased MoH A and was looking forward to playing, but things were not to be so easy. My first problem was with incompatible drivers, which required a fix that I downloaded, and that got me over the first hurdle, but now right when the installation bar gets to the end it starts to "roll back" (meaning it uninstalled itself). No matter what I do, I can't get it to finish installing without it undoing the whole thing! I heard that this can happen when the Internet Connection Sharing (ICS) service is not started, but I can't start it! I don't know if its for that reason it won't install or some other reason, but if you can help me please do!
My OS is a 32-bit Vista if that's any help. Thanks
