I updated 2 PC's to 4.7 the day the update came out and SC went from running 4.6 just fine on both PC's to cant even boot up the game from the launcher on either computer. I get the 3221225477 error every time. If it was just one of the PC's then I would just think it's on my end, but TWO, I dont think so. I've verified the files many times, uninstalled and reinstalled the game many times, updated graphics drivers, rolled back graphics, made sure I'm running as admin.......on and on and on. Please help.
