Sometimes it is a computability issue though, I have windows 7 and have no compatibility issues. But you can just right click on the CivIV icon and go to compatibility and then click Windows Vista Service Pack 2.
You can also try other compatibility modes.
Since I have Windows 7 and not Vista, I can't click on Vista Service Pack 2.
I am no expert and I am not sure if this will work. Maybe you can try to do an auto update online. Just go to options and let it auto update or you can manually find a 3.19 online.
I did the auto update. That's how I got the download. And installation starts okay, it just doesn't doesn't get past the start window.
