Can't reinstall or update game.

I had the same problem and finally found a solution.

First, I aborted the update of the game (in my case Forza Horizon 5). I started the XBox App, hit the three dots beside the game, picked "Manage Install" and there I could click "cancel installation". Good, the game was playable/visible again.

To pinpoint what exactly goes wrong, I looked into the Event Viewer under "Application and Service Logs > Microsoft > Windows > Store > Operational". There were several errors pointing to that error code 0x80071127. For example this one:

XvcDataSource_RemoveJunction.RemovingReparsePoint \\?\D:\WindowsApps\Microsoft.624F8B84B80_3.414.967.0_x64__8wekyb3d8bbwe
Error: The reparse point attribute cannot be set because it conflicts with an existing attribute.
Function: XvcDataSource::RemoveJunction

I inspected that junction (using `fsutil reparsepoint query` but it didn't look suspicious. No idea where the conflict comes from. Unfortunately, I am not allowed to fiddle in that folder; not even as System or TrusterInstaller user.

So I booted a Linux live CD and went to the WindowsApps directory to delete the problematic junction (In my case "Microsoft.624F8B84B80_3.414.967.0_x64__8wekyb3d8bbwe", which is a specific version of Forza Horizon 5): `rm Microsoft.624F8B84B80_3.414.967.0_x64__8wekyb3d8bbwe`.

I rebooted to Windows, went to "(System) Settings > Apps > Forza Horizon 5 > Advanced Settings" and hit "Repair" followed by "Reset". Then I opened the XBox App, searched for Forza Horizon 5, hit "Install", picked the same location I had before, and after a few seconds it registered that all files are already there and it was fine again. Then I went to the Windows Store, hit "Get Updates" and it finally started successfully updating the game. No conflict anymore.

(I had to do this for three games ... all work now.)

Edit: I just realized that my system showed a lot of traffic, so something was apparently downloading ... a lot. Neither Windows Store nor the XBox App showed any active downloads, so I assume my "reinstall" from above triggered some background download that is redundant now. I wen to "(System) Settings > Apps > Gaming Service" and hit "Reset". The downloads stopped. So I guess I have a clean state now - again. The games still work.

Hello dear Gamer, first it's a pleasure to be able to help you today.

My name is Vinicius.

I am a gamer and independent advisor on the XBOX community platform.

Hey LazoOfTruth, how are you today? Hope you're well.

So, let's try this, first, make sure your windows and all its services are up to date:

Open Settings, click Update and Security and then Windows Update;

Click Check for Updates;

Click the Download and Install Now option, if available;

Also, check the Microsoft Store for any updates on the Xbox apps and its services.

______________________________________________________________

Then try this:

Go to windows settings > apps > search for gaming services app > click on it and select advanced options.

After that, click repair and then restore, open the app and try again.

Then do the same for the Xbox app:

Go to windows settings > apps > search for Xbox app > click on it and select advanced options.

After that, click repair and then restore, open the app and try again.

______________________________________________________________

Then, try to uninstall and install the Xbox app.

______________________________________________________________

If it still doesn't work you're going to uninstall the games services using a powershell command, then you're going to open the gamepass app, it will ask you to download and install the game services again :

In the windows search bar type Powershell > Right click and select open as administrator > Type the command: "get-appxpackage Microsoft.GamingServices | remove-Appxpackage –allusers" > Wait for the process to finish and then restart the PC, then open your Xbox gamepass app, it will ask you to install the gaming services again, install it and try again.

______________________________________________________________

If neither of those procedures works, try to restore your PC's OS via the ISO image tool, using that tool you will be able to maintain your installed games and files.

Hello, first of all thanks for your answer. I will explain it in English so everybody can understand what's happening.

I installed the game, played it some hours and quit, then it suddently started to update but the update was reinstalling the game, so i did cancel it and tried to start the game. Since this, the game does not start, i tried to uninstall and reinstall it,
but i can't reinstall it because it shows the game already is in my library.

So, i can't install and i can't play it.

Hello AromaticSpy505

Normally Once an update had been applied to the Game or Windows this can't be reverted since the update will reinstall automatically if you Factory Reset or Uninstall the game

I also have this issue... DO NOT try uninstalling and reinstalling! Tried uninstalling the game and reinstalling over a 2.0kb update, now I can't install the game at all! Hope they fix this issue soon...
