  1. this is the longest proses i have gone through just to download an OS. 4hrs 22min on high speed internet. i think files takes long to build up. pop some popcorn and relax

    1. Yes sometimes it does take that much time. You can try editing the Configfile where set AddUpdates value to 2, it’ll be done under 30 minutes then.
