ERROR 0x803f81f5 Minecraft

Question

I've been getting this error 0x803f81f5 on my new computer when installing minecraft

Even thought at it shows zero devices ar connected at my store, and only 3 divices on my account. I've donne all sorts of things,

• defined my new computer as a offline account
• wsreset.exe
  -Press Windows + I key together to open Settings.

1. Click on Update & Security and then click on Troubleshoot.
2. On the right hand pane scroll down and look for Windows Store Apps.
3. Click on it and select Run the troubleshooter.
4. Follow the on-screen instructions.

-Press Windows + X keys together and click on Windows PowerShell (Admin).

1. Now type in the command and hit enter: Get-AppXPackage WindowsStore -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
2. Restart the PC.

The support said that reseting my computer "could help", but i've seen other people that had the same issue at the forum and said that it did nothing. Anyone has any other solution?

Hello Miguel,

Try the below options (I hope one of them fix the mentioned issue)
"Microsoft Store licensing limits don’t usually block installations like this"

1. Fix account:

1. Open Settings --> Accounts --> Email & accounts
2. Remove your friend’s account completely
3. Go to Settings --> Accounts --> Your info
4. Make sure your main account is active

Clear Minecraft Launcher Cache:

1. Close the Minecraft Launcher and any related processes
2. Press Win + R, type %appdata%\.minecraft, and press Enter
3. Locate and delete the file named launcher_accounts.json.
4. (Optional) If you see folders named launcher_cache, webcache, or webcache2, delete those as well.

Additional:

1. Open the Start Menu, search for Credential Manager, and open it (Under Generic Credentials):
2. Look for any entries containing "Minecraft", "Xbox", "Xbl", or "MicrosoftAccount:user=". and Select Remove.

Sign Out of Linked Apps:

(Xbox App + Microsoft Store + Windows Accounts)

Then:

1. Open Microsoft Store
2. Click your profile icon
3. Sign out
4. Sign back in with your account (the one that owns Minecraft)

2. Reset Microsoft Store and Xbox services

1. Press Win + R, type:
2. wsreset.exe

Then reinstall or repair:

Xbox App

Xbox Live Services

Minecraft Launcher

To do this:

1. Go to Settings --> Apps --> Installed apps

Find each app: Click Advanced options --> Repair --> Reset

3. Check Gaming Services

1. Open PowerShell as admin and run:
2. get-appxpackage Microsoft.GamingServices | remove-AppxPackage -allusers
3. start ms-windows-store://pdp/?productid=9MWPM2CQNLHN
4. Reinstall Gaming Services from the Store page that opens.

Fix license sync

Open PowerShell (Admin) and run:

1. Get-AppxPackage *xbox* | Remove-AppxPackage
2. Get-AppxPackage *windowsstore* | Remove-AppxPackage

Then reinstall Store components:

• wsreset.exe

Restart your PC.

4. Switch network / disable VPN / proxy:

A. Reset network:

Open Command Prompt as admin:

1. netsh winsock reset
2. netsh int ip reset
3. ipconfig /flushdns
4. Restart your PC.

B. Check proxy

1. Settings --> Network --> Proxy
2. Turn OFF everything unless you really use a proxy

C. Turn off VPN completely

• Even installed VPN apps can break Microsoft services.

5. Check Windows services

1. Press Win + R --> services.msc
2. Make sure these are running:

• Xbox Live Auth Manager
• Xbox Live Game Save
• Xbox Live Networking Service
• Windows Update

6. Make sure Windows is fully updated & Check date & time.

7. If nothing works (without full reset)

1. Try creating a new Windows user:
2. Settings --> Accounts --> Other users
3. Add a new user
4. Log into that account
5. Install Minecraft there

// If it works >>>>> your main Windows profile is corrupted (not your PC) //

Last Option: FULL RESET:

1. Try an in-place repair install of Windows 11:
2. Download Windows 11 ISO from Microsoft
3. Run setup
4. Choose Keep personal files and apps
5. This fixes broken system components without deleting your data.

II hope this helps.
