This is basically the process of Uninstalling Warzone from the list of COD Series. As reported by several players, this has successfully resolved their issue of COD MW3 not launching or giving the said error code.

You can try the rest of the fixes, which I will list, but honestly, these are just some basic fixes that you should only try if the above method did not work for you:

  • Update the Graphics Driver to the latest one.
  • Update Windows to the newest version.
  • C++ and Framework update is also needed if not done.
  • Verify the Integrity of game files. If any file is missing or corrupted, it will be downloaded.

I personally have Warzone installed, and it is not giving me any issues so far. But yes, if you face this issue, make sure to remove Warzone until the devs decide to patch it anytime soon. I hope you can play the game properly after doing this fix.
