halo MCC dlc install issue

I'm getting this from trying to Install the "Halo Nightfall" DLC that comes with the MCC.

To those having install issues, do as other have said, make sure to update halo mcc and make sure you have the disc in when installing, the campaign resides under the halo 3 campaign in halo mcc.

Thanks for contacting us my name is Samy, I am advisor independent and I will be helping you today.

How are you, mate?

These 2 games are DLC's for Halo MCC, you have to purchase and install Halo MCC to be able to access this content in-game.

Try install it from Manage a game menu in game list for Halo MCC. You will see all content and DLC try reinstall it from there.

Good luck!

Halo 3: ODST was not included as part of the Master Chief Collection. There was a redemption code sent out for it for some users of MCC as a make-good, which added the single-player version of ODST to the MCC. If you redeemed it then, then it would be available
as DLC on the account that redeemed it.

Go to My Games & Apps -> Games -> Halo MCC and press Menu, then choose Manage Game. If this account redeemed it, it will appear in "Ready to Install".

If you own the Xbox 360 version of Halo 3 ODST, you can install the single-player version through back-compat.
