I like the idea. But I don't think i would work. Some users on the forum can't even use WinRAR to extract a file, I don't think they would be able to do this. However It is a good idea for the people who know what they are doing.
to the forums. Emergency 3 DOES work on Windows Vista. I was able to run EM3 on a laptop with Vista with no problems. To help us fix your problem can you post a logfile and dxdiag file please. Look in the FAQ section if you don't know how to get these files
