This is a quick tutorial video of how to launch Black Ops 2 on Steam without getting the "Unhandled Exception Caught" error message that crashes the game.
First, you will navigate to:
Steam settings
Interface
In the Client Beta Participation section, click on the drop-down menu that has "No Beta Chosen" selected, and choose "Steam Beta Update"
Restart Steam when prompted
Launch and play BO2 with no problems at all!
I included a small amount of gameplay when I re-launched the game after selecting the beta, to show that the game will NOT crash. Go enjoy some real COD frfr!!!!
