I have installed successfully Age Of Empires III on my computer but when I try to run the game it wont load. Game shows some long error messages mentioning d3dx9_25.dll and MSXML 4 and after that it returns me to desktop. I have tried to figure this out but without luck. Computer configuration meets recommended system requirements, so I think that this problem is not hardware related. Do you know what the problem is?
You should visit Microsoft web site and download latest update for DirectX 9 and MSXML4 (this is Microsoft XML parser and it is needed for some game functions to perform correctly). Install both programs and restart computer. After this you will be able to start the game normally and play it.
