Halo reach can't install

I saw that on Xbox Backward Compatible Games | Xbox it said that halo reach was backwards compatible, but when I put the game into my console it says that it is not backwards compatible.
Assassin’s creed 2 is also on the list but installing that worked.

That happened to me also. I restarted the box with the disk in, then eventually it told me it needed an update to play the game. Try that out. The update is a little over 7gb.

Maps are on separate files.

I have the same issue :confused:
