Minecraft error code 0x803FB107 means the platform (Xbox, Microsoft Store, or PC) cannot verify that you own a valid copy of the game.

How to Fix Error Code 0x803FB107

  1. Sign Out and Sign Back Into Your Microsoft Account

    Make sure you sign in with the exact Microsoft account used to purchase Minecraft. Using a different account will not resolve the error.

  2. Restore Your Microsoft Store Licenses

    Running wsreset.exe will temporarily close the Microsoft Store. Do not interrupt the process while it is running.

  3. Clear the Microsoft Store Cache

  4. Check for Windows and Microsoft Store Updates

    Back up any active Minecraft worlds to a USB drive or cloud storage before performing system updates, as a precaution.

  5. Re-register Microsoft Store Apps via PowerShell

    Only run PowerShell commands as administrator when you trust the source. This command only re-registers existing apps and does not delete any data.

  6. Verify the Correct Account Owns Minecraft

  7. Reinstall Minecraft as a Last Resort

    Before uninstalling, make sure your Minecraft worlds are backed up to OneDrive or an external drive if you have not enabled cloud saves, as local worlds may be deleted.

When to Call a Professional

If you have confirmed the correct account owns Minecraft, followed every step above, and the error persists, contact Microsoft Support at support.microsoft.com or Xbox Support at support.xbox.com. You should also contact support if your purchase history does not show Minecraft despite having paid for it — this may indicate a billing issue or account compromise that requires a support agent to resolve. Additionally, if you believe your Microsoft account has been hacked or your purchase was removed without your action, contact Microsoft immediately to secure your account.

Frequently Asked Questions

What does Minecraft error code 0x803FB107 mean?
Error 0x803FB107 means the Xbox or Microsoft platform cannot detect a valid ownership license for Minecraft on the account currently signed in. It typically occurs when you are signed into the wrong Microsoft account, your license data is cached incorrectly, or the Microsoft Store needs a refresh.
How do I fix Minecraft error 0x803FB107 on Xbox?
On Xbox, sign out of your account by pressing the Xbox button, going to Profile & System, and selecting Sign Out. Wait 30 seconds, sign back in with the account that purchased Minecraft, and relaunch the game. If that does not work, try a full power cycle by holding the Xbox power button for 10 seconds until it shuts off, unplugging the power cable for 60 seconds, then restarting.
Why does Minecraft say I don't own it when I already paid?
This usually happens because you are signed into a different Microsoft account than the one used to purchase Minecraft, or because the Microsoft Store license cache is corrupted. Sign into account.microsoft.com and check your order history to confirm which account owns the game, then sign into that account on your device.
Will I lose my Minecraft worlds if I reinstall to fix error 0x803FB107?
Worlds saved to Microsoft's cloud (via Xbox account sync) will be restored after reinstalling and signing in. However, local worlds stored only on your device may be lost. Before reinstalling, manually back up your worlds by copying the saves folder — on Windows it is typically found at %AppData%\.minecraft\saves — to an external drive or cloud storage.
Does running wsreset.exe fix Minecraft error 0x803FB107?
Yes, running wsreset.exe often fixes error 0x803FB107 because it clears the Microsoft Store's cached data, including corrupted license information, and forces the Store to re-verify your game ownership. To run it, press Windows + R, type wsreset.exe, and click OK. Wait for the blank window to close and the Store to reopen, then try launching Minecraft again.
