I bought halo mcc on the microsoft store on my pc and can't download it on my xbox

Unfortunately that game is not a Play Anywhere game, so if you want to play on the Xbox, you would need to purchase the Xbox version.

I am also having this issue, I can't play my EA UFC or Halo MCC digital downloads. I would have never bought these games digitally if I knew this could happen

Halo 3 ODST is an add-on for the MCC so it needs the MCC installed as well. Have just checked the Store and ODST can't be bought separately so it must be the MCC add-on:

https://www.xbox.com/en-GB/games/store/halo-3-odst/9N007VX9RGXZ/0010

As you will see on that page:

"This content requires a game (sold separately)."

Game meaning MCC

So when it first came out I bought the halo master chief collection, I can not access it on my xbox one I can only access it on the pc does anyone know why it happened or how to fix it? I bought it using my xbox not my pc. Plz help

Hey Dvn01, can you please explain why you are not able to access the Halo: MCC on the Xbox one?

On Xbox One it will be part of the Halo MCC. The one listed separately on the store is for PC. So if you purchase it, you will own it on PC.
