MSIX file for Gaming Services

Hello Durpybaby123, I am an independent advisor and I will be happy to help you today. My name is Khaji

I understand that you are trying to install an untrusted MSIX file on your Xbox and are encountering an error (0x800B010A).

Here are some steps you could take to fix this problem:

Verify digital signature: You can verify the digital signature of the MSIX file. Go to the digital signatures tab, select the certificate and click details. In the next window, select “View certificate”. In the next stage, select "Install certificate"

Use PowerShell: Another way to install applications is to open PowerShell (as administrator) and run the command Add-AppxPackage -Path C:\\Path\\App-Package.msixbundle. This command will also work for the “appxbundle”, “msix” or “appx” extensions.

Please note that these steps are generally for Windows and may not work exactly the same on Xbox. I would recommend that you contact Xbox support for help specific to your console. I hope this helps you!

Okay, it was worth a try to see if the closest official functionality was suitable. Unfortunately, unofficial methods are not appropriate for discussion in an official area, so instead, here are some names and factual information to get you started on your
journey:

• The Microsoft Store app was formerly named the Windows Store.
• Many games in the Store are built on the Universal Windows Platform (UWP).
• Downloads from the Store typically take the form of a package with the following file extensions: .appx, .eappx, .appxbundle, .eappxbundle, .msix, .emsix, .msixbundle, .emsixbundle (with encrypted editions starting with an E)
• Files for
  Windows apps are stored in the WindowsApps folder in Program Files.
• MakeAppx.exe and
  
  MSIX Packaging Tool can create packages for Windows apps.
• The PowerShell cmdlet
  Get-AppxPackage can list installed apps and games,
  Add-AppxPackage can install them, and
  Remove-AppxPackage can uninstall them.
• App Installer can be used to install packages through a user interface instead of through PowerShell.
  

I resolved by myself; since the services weren't showing in service tab I just installed gaming services on another PC exported the registry files named "GamingServices" and "GamingServicesNet" located in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
and run the reg file on my PC that had problems.

Now all the games finally download and run without problems

I'm really glad it worked! Those steps reset the Xbox app and the Gaming services files and re-register the apps - sometimes corrupted files can be the culprit of a sync issue with a game license or subscription. They also clear any temporary file and cache from the Microsoft store and the Xbox app. This makes the Xbox app and the Gaming services sync again with the Xbox servers to check for the game license or for any active subscription.

Its not a service they are all up. Check you Game download Server config file.
