Hello I recently re-installed CIV4 because I want to play a big marathon game and try take over the world again. However I have a problem. BTS works fine, but the original Vanilla does not start up. "This program has known compatibility issues". Warlords does the same. It is BTS I want to play however I want to use a mod. The mod is called Civilizations, it slows tech and allows 50 nations to play, adding extra countries to to allow that. For some reason when I go into advanced options and load the mod it says "Civ4 has stopped working" similar to when I try to launch warlords so I assume the problem is related to the same issue causing the vanilla and warlords version not to work. Can anyone help with this? I have tried different compatibility modes for the vanilla version as well as in administrator mode. No success.
