I've recently downloaded the game and I keep on getting this error whenever I try to launch it http://prntscr.com/g7bh70, yes I have launched it in administrator but it still gave me the same error. What else can I do? And forgive me if this isn't the right area to submit this. I downloaded mists of pandaria 5.4.8 .
Follow these steps:
1) Restart your PC ( this is important)
2) close your Torrent client and move your WoW folder away from your Torrent's download destination
3) now right click on WoW folder> Properties> remove "read-only".
