Its probably downloading the updates for the game at the same time its installing. If thats the case, its probably your slow internet connection (unless im wrong) and the fact millions of users are also downloading the updates for their games.
That's trash peter. I tried disconnecting my internet service and power cycling down my xbox one. Then turned it on and tried installing my game without internet connection. I got message saying I had to have internet connection in order to install game
on hard drive. Idk. Microsoft needs to fix this
Been having this problem as well but the 'disconnecting from live' isn't working. it took me literally over 24 hours to install Battlefield 4 and it's driving me crazy. Any other help would be appreciated.
