i redeemed a key on microsoft for the xbox live for pc, but i do not have the game in my...

basically it won't show under the xbox app, use the windows 10 store.

To download the games that were purchased or redeemed using a prepaid code on Windows 10, kindly perform the following steps:

1. Using your Microsoft account, sign in to the PC where you want to install your games.
   
2. On the Start screen, select the Store icon.
   
3. In the Store, select Games from the menu.
   
4. Browse and select the game that you purchased or redeemed using a prepaid code.
   
5. Select Install.
   

Make sure that you are logged in with the Microsoft Account that you used to redeem the game's prepaid code.

However, if you sill can't find the game, it would be best to get in touch with our live support Contact us | Xbox Support to check your account from their end.

Hello,

I don't quite know what you mean by the PC being old or new, that shouldn't matter either way. If you purchased the game via a retail disc when you first redeemed the key it should have been redeemed to a Windows Live ID account.

If your trying to now use another Windows Live ID than the one you used before you will not be able to play the game as the game would be registered to another Windows Live ID. Same goes with DLC, if you've redeemed the codes when you were on another PC using
another Windows Live ID it would not be possible to redeem the same content again.

So to review, when you redeem a key on a specific Windows Live ID, you need to use that same Windows Live ID for all future content in relation to that game as well as the game on a re-install. When you stop using a PC you should also uninstall the game on
that PC as the activation key (redemption key) can only be active on 1 account / 1 PC at a time.

If you require further assistance with this specific issue please follow the link given by Mister Gwyther in the post above mine and speak with a GWFL Support agent.

The Xbox app is just a standalone app, which can be used to download games to PC. You do not need an Xbox games console to use it. Flight Simulator is an Xbox Live enabled game for PC and Xbox. That will be why you were given the link for the app, so you could download the game from the app. You log in with the account you used to redeem the code, and download the game. The version of the game you need is the PC version, which you can get from CD Keys or directly from the Microsoft Store on Windows 10.
