Re: Repairing takes forever
@noxvortexx Origin has had this issue for a few months now, and it's not clear why, although a few have said it helps to disable their antivirus program before repairing. Part of the problem is, Origin is going to be replaced by the new EA Desktop App sooner or later, and most of the development resources are going to the new app.
Anyway, you should be able to cancel the repair of a given pack by hovering over the download manager in the lower left corner of the Origin window. There should be an X icon for each download or repair in the queue.
