Forza Horizon 5 error code 0x8007042b on Windows 11 pro

Yes, I attended two other users having this issue yesterday. I'm not sure if the game offers Windows 10 compatibility. To see the available options, please right-click the Forza Horizon game executable > Click properties > Go to compatibility tab > Check run this program in compatibility mode for > Select your choice.

If you don't know where the installation path is (that have the game executable file), please go to Start > Find Forza Horizon > Right click on it > Click on More > Open file location.

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

If you haven't tried already, you could try to reinstall the gaming services and remove your Xbox accounts from the computer to sync again with the servers.

- Go to start > Search for PowerShell > Right click > Run as administrator. Type the following command and press enter:

get-appxpackage Microsoft.GamingServices | remove-AppxPackage -allusers

- Press Windows + R and type in "regedit". Press enter.

- Search for HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services

- Delete the folders "GamingServices", "GamingServices.net" (if they're still there).

- Click on Start > Search for Credential manager > Windows credentials. Search for Xbl|DeviceKey, click on it and then Remove. Also, remove all the XblGrts and XboxLive credentials.

- Delete Accounts and Cache folders at:
%userprofile%\AppData\Local\Packages\Microsoft.XboxIdentityProvider_8wekyb3d8bbwe\AC\TokenBroker

- Go to Start > Settings > Apps > Apps & features > Microsoft Store > Advanced Options > Repair, then Reset.

- Go to Start > Settings > Apps > Apps & features > Xbox App > Advanced Options > Repair, then Reset.

- Press Windows + R. Type TEMP and press enter. Delete all the files inside this folder. Repeat this step by typing %TEMP% and Prefetch. Delete everything on both folders too.

- Press Windows + R. Type WSRESET and press enter.

- Restart your computer. Run Powershell as administrator and run the following commands (one at a time):

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

(this command can show you some errors, this is normal, just wait until it finishes)

start ms-windows-store://pdp/?productid=9MWPM2CQNLHN

- Install the app on that page and select Yes when you receive the User Account Control (UAC) prompt. Also sign in on the Microsoft store with your Microsoft account.

- Restart your computer one more time. Check your computer region/country and language and please make sure it is the same as your Microsoft account (https://account.microsoft.com/profile). Also check your time zone and date/time is correct.

- Go to Start > Type Services > Open it. Find all Xbox Services (Xbox Accessory Management Service, Live Auth Manager, Live Game Save, Live Networking Service, Gaming Services). Right Click > Properties> Set the startup type to Automatic. Also Start them.

If the issue persists and even doing a in-place upgrade did not help, I would say you would need to reach to the game developers and report this bug. I can give you more troubleshooting steps to do, but this looks like a game issue since other users are reporting this same error on Windows 11.

Waiting for your follow-up.

Thank you for you answer, sadly these steps did not solve the issue, is there anyway to launch the game in compatibility mode for Windows 10 ?, otherwise I will report this bug to the game developers, since you have mentioned that other users are reporting this same error on Windows 11.

The game is compressed using NTFS compression to reduce it's size, could this be the cause of the issue ? because the game was working even compressed before the latest game updates, also I did contacted forza support and they told me to report a game bug to Microsoft but I do not know how to report it.
I also found this solution in the screenshot below but I do not have the Steam version and I there is not delete option when searching for Forza in C:\Users\CJ\AppData\Roaming

Thank you for your reply, I have followed the steps you have mentioned but none of it worked, the issue only happens with FH5, the other FH4 is working (both of them are from Microsoft store).
