So, I installed Civ. IV on one of my computers, and it worked fine. It updated ok, and currently is running well. I want to install it on another computer, so I did, then updated to version 1.74 as prompted. But, when I do (I tried on 3 different computers, same result) I get some error that says something like "unable to find valid source" when it is about to finish installing the update. I close that and it says it updated, and no surprise, when it starts, it says
"This application failed to start because D3DX9_32.DLL was not found. Re-installing the application may fix this problem"
Then I try to uninstall it, and something goes wrong, and I cant even uninstall (well, I did with ccleaner eventually). Any suggestions? Any help would be appreciated.
