I recently bought the Limited Edition Halo 5 Xbox One Console and a couple days later I bought Halo Wars (Xbox 360 Disc) because I was told it was backwards compatible. I tried to play the disc but my console said I had to install an update first. I tried installing the update and it was downloading up until it got to 49% aka 3.17GB out of 6.37GB, once it got to that point it completely stopped installing and said “Something interrupted the download” and it wouldn’t proceed to download no matter what I tried. After about 4 more times of trying to install it and 4 more times of it stopping at 49% aka 3.17GB of 6.37GB I decided to go back to the store where I got the disc and try another disc. Even that second disc kept stopping at the same point so I called Xbox Customer Service. Before I got someone on the phone I decided to try installing another supposed “backwards compatible” game (Halo 4). The installation of Halo 4 worked! I finally got someone on the phone and explained the situation to them, they had me go into the settings and clear a few settings which initiated restarts for each change. Just before doing the final step, which was putting the disc back in and trying the install again, the call was disconnected. I tried to install it again but it stopped at the exact same place. I then decided to try installing a different supposed “backwards compatible” game (Halo Reach). The download for Halo Reach worked just like it did for Halo 4. The main issue is that Halo Wars refuses to download past 49% and keeps stopping at 3.17GB of 6.37GB, it has NEVER reached 3.18GB out of 6.37GB in all the 12 times I’ve tried installing it. any help resolving this matter would be greatly appreciated.
I’m really not sure what might work in fixing this. You could try going into settings, where it may be possible to clear the “Persistent storage” (content cache) for your Blu-ray drive. This might help, or it might not. You could also try resetting your modem or router.
Have you tried hard resetting your Xbox One? That usually fixes a ton of problems people experience with it (it’s like restarting your computer because Google Chrome won’t start for some weird reason)
