Hello, MartinHextall. Thanks for reaching out! My name is Lucas, and I'm an Independent Advisor and a Microsoft user just like you. I'll be happy to assist you today.

I'm sorry about the inconvenience. Are you trying to play it on Xbox or PC? Please tell me what console or Windows version are you running.

Did you purchase it on Microsoft/Xbox store? Can you see the purchase showing as completed here?

Waiting for your answers, my friend.

Hi,

What version of the game do you own and how are you trying to upgrade it?

My understanding is that you need to purchase the upgrade directly via the store on the Series X.

Code:

CALL OF DUTY®: BLACK OPS COLD WAR
Microsoft Xbox

Thanks. It was purchased for me through Walmart and redeemed at my Xbox account

From what I can tell, to access the Series X version of the game, you need the Cross-Gen bundle...once you buy that, you should then be able to download and install the Series X version. Without the cross-gen bundle it will, presumably, just install the XB1 version

From the Store page:

"For digital owners of the Call of Duty®: Black Ops Cold War Standard Edition, this upgrade will unlock the Call of Duty®: Black Ops Cold War Cross-Gen Bundle, giving access to the Xbox Series X|S version of the game. After upgrade purchase, search in the Xbox store for the Call of Duty®: Black Ops Cold War - Cross-Gen Bundle to install the Xbox Series X|S version of the game."

What version of the game have you purchased? The series X/S versions will not be available to Pre-install until November 10th 2020 according to the following:

Without further information I cannot pin down the exact issue but hope this works for you!
