When installling the game I am asked to install OpenMG. Why and how do I get around this?
OpenMG is an application unrelated to Civilization 4, however windows can sometimes confuse the two applications. To continue the install of the game, you need to do the following :
Goto 'My Computer' and right click on the DVD drive, select open.
Find the file called 'setup.exe'. Double click on setup.exe to install the game.
