Modern Warfare 3 Crashes on Launch: How can I get it running?

Solution 1:

I think you'd need to contact IW and give them the debug information, as only they would know what those debug codes mean. This could be done via the forums.

Otherwise you could try to repair it via Steam (redownload/repair).

Solution 2:

In Steam's options, disabling the in-game overlay means the game now functions.
