Everything seems to be fine, update finishes and I back out the game like the guide tells me. Then windows installer runs for a few seconds and then I get this error message.
I'm running on windows 7.
I've tried everything from manual updates to running in compatibility mode. I even wiped GTA off my hardrive and tried again, still getting the same problem.
Windows 7 Home Premium 64-bit
Intel® Core2 Quad CPU Q8300 @ 2.50GHz (4CPUs), ~2.5GHz
