Unity Games Crash on Startup

I have been trying to run Blizzard’s new pc game Hearthstone but every time I try to run it the game crashes and the error log says its something to do with unity.

I tried running another pc game that also uses unity with similar results.

How can I fix this? Here’s one of the error dumps:

I should have come back sooner… this is now fixed for me… it was indeed an issue with windows… i have since re-installed windows on my Rig, with a different disc. and the problem went away… to be totally honest i was running a not very official copy of windows, which was the reason. not sure what about it UNITY didn`t like but its working now :slight_smile:
