I have tried everything on http://www.keenandgraev.com/2012/05/12/diablo-3-stuck-updating-setup-files-fix/ and those fixes don't work.
I am was using Windows 8, and I reformatted to Windows 7 both 64 bit, and I am still stuck at the same place, and I have tried all the same fixes with both operating systems. Can anyone help, I would really like to play tonight?
Edit: It gets about 60% through, before getting stuck. I
I have tried opening task manager, and whenever I end the Agent process the bar goes back to about 20% then moves back up to about 60%.
Edit: I went to my mom's house, and tried installing it on windows xp, and I'm having the same problems.
