How do I get the store to recognize I preordered the vault edition for Modern Warfare II so...

Hello, welcome to Microsoft Answers Community.

Yes. You will need a Microsoft Account to download games from Microsoft Store or Xbox, and play them in Online mode.

However, neither the Vault Edition nor the Cross-Gen Bundle of Call of Duty®: Modern Warfare® II is included with Xbox Game Pass. Therefore, you do not need an XGP membership.

*For Call of Duty®: Modern Warfare® II - Vault Edition, please visit Buy Call of Duty®: Modern Warfare® II - Vault Edition | Xbox;
*For Call of Duty®: Modern Warfare® II - Cross-Gen Bundle, please visit Buy Call of Duty®: Modern Warfare® II - Cross-Gen Bundle | Xbox

*For the official page of Call od Duty: Modern Warfare II, please visit https://www.xbox.com/en-US/games/call-of-duty-modern-warfare-ii.

Best Regards

Hi, I found that strange… what edition was the one that you purchased?
Vault or Cross-gen?

In the meantime tell me, if you go here and sign in with the account that owns the game. Are you able to see an “install” button? Or just “buy”?

Vault:

Cross-gen

Please try reinstalling the game from your library or remotely from here:

Vault: https://www.xbox.com/games/store/call-of-duty-m...

Standard: https://www.xbox.com/games/store/call-of-duty-m...

I apologize but there is no option to upgrade if it’s from a game sharing only. I also checked the “ Call of Duty: Modern Warfare II - Vault Edition Pack” but it’s not available on the store, only redeemed code.

The exact purchase was Modern Warfare II :Vault edition digital download for S/X
