I can't seem to download Halo Wars on Xbone

So I went out and picked up a physical copy and every time I try to install it it keeps telling me its not playable. But I can go to the store and buy a copy to install. Anyone know any fixes or experience this?

same thing happened to me and i contacted microsoft support and they told me my disk was broken my console needed to be repaired yada yada yada…
Anyway I didnt believe that anything was broken because I hadnt touched the disc since I had my 360 and it worked fine then. So I kept trying and eventually it worked when I cleared the persistant cache in blu ray player and hard reset my xbox and unplugged it.
