I think I may have found a solution.
I posted this in the [343 RESPONSE] HALO WARS 2 INSTALLATION STOPPED thread. But I wanted to get this out there as as fast as possible, so I’m creating a new thread for it also.
I really didn’t want to factory reset my Xbox, so I tried deleting the 3 other profiles on my xbox. The installation used to always stop at 18%, but now it’s at 44% (started at 8:00 AM, currently 4:17PM).
I have to leave now, but I’ll leave it running. But I won’t know if it worked till Monday. Might be a fluke. Might be the actual solution. We’ll see…
