Multiplayer stuck at 71% for 4+ hours

I was stoked to get this game, preordered it, picked it up at midnight, started the install. Halo CE and Halo 4 downloaded really quickly, and I made sure to leave my Xbox on all day. Since I got back from lunch at like 1:30, the multiplayer installation has been stuck at 71% ever since. Any help? What happened to the days where you could buy a game, plop it in and just play it? I’m really disappointed.

I had this problem as well. Game said it was installed, but Halo 2, 3, and Anniversary were ‘not installed’. I unplugged my X1 and plugged it back in, and for whatever reason it solved it. All five games displayed as fully installed after that.

Worth a try I guess, not much to lose in trying.
