Restarting first time setup for games on Steam

So by accident for XCOM: Enemy Unknown, I cancelled the VC-Redist setup before it went all the way through, and I think that's the result for me getting green bars when I start the game, and later, a Blue Screen of Death (BSoD). Is there any way to fix this?

The intro screen looks like this:
