What do you do? Why you run the patch of course! You run the patch and then the stupid patch stops halfway due to some error in the patch. You report the matter to the publisher and try to enjoy the game without the patch. Ho and behold, you find that this cannot be done. The game won’t start without the patch because it’s mandatory. So now you are struck with a game you bought but can’t run due to a patch error that you can’t solve.
What do you do? If you are me, you will uninstall the stupid game, curse the publisher and play Skyrim
