Download from microsoft account

What game is it? And this is on Xbox One? I would recommend navigating to the store page for the title, if it's not updated in your "My Games & Apps" section, but still associated to the account, it should let you download it directly.

You might want to check if the title is also already in the Installed section of My Games & Apps? When you redeem a game, depending on your settings, it could automatically start to download the title, so see if it's listed there or in the Queue already
downloading.

Hello, Number1Yeti

The device may not be showing on the app due to it not being listed on your Microsoft Account

You need to add a device to your Microsoft account before it's listed in your devices. Here's how you can add a device:

• Sign in to your Microsoft account on an Xbox or PC.
• Download an app or game from the Microsoft Store .
• Go to account.microsoft.com/devices, select Don't see your device?, then follow the instructions.
• On an iOS device: Download Microsoft Edge from the Apple App Store and sign in with your Microsoft account.
• On an Android device: Download Microsoft Edge, Microsoft Launcher, or Your Phone Companion from the Google Play Store and sign in with your Microsoft account.
• MacOS devices can't be added at this time.

you don't get a code if you purchased from the microsoft store, it will be in your purchase history or download history to download to your computer, it has to be downloaded from the account that made the purchase.

Hi there, have you waited 30 days since downloading the profile to the Xbox 360 console? If you made any changes and didn't re-download the profile, I don't think the 30 days cones in affect.

Note You also must wait 30 days after your gamertag is downloaded from Xbox Live before you can switch that gamertag to a different Microsoft account.

Try to download the launcher from Microsoft Store and sign-in with your account and see.
