I had to pass this "Updating setup files" before by just going into control panel > add and remove programs > and continuously delete the beta, eventually it worked.. now there's no programs to delete I've tried different solutions however I'm under the impression not many have a windows XP so I don't see exactly what they see. So I'm stuck waiting for blizzard to fix this problem... This is the first time I've pre-ordered a game from Blizzard does this always happen with new games they release?
