I've recently purchased hearts of iron anthology for my PC (laptop)i'm running windows vista. After i inserted the disc and selected install it comes up with the menu list of hearts of iron, hearts of iron 2, doomsday then armageddon. selecting Armageddon it then just tells me that it had a problem loading and the computer will tell me if there is a solution. I still have doomsday installed on the computer could this being affecting the loading of Armageddon or would i have to install in turn, Hearts of iron, then hearts of iron 2, then doomsday and finally Armageddon. any help would be greatfully recived.
