Hi Edvin Niin,
Since the error code 0x803F8001 is commonly related to a licensing or account entitlement check, the issue may be with how the game license is being validated rather than the installation itself.
A couple of additional checks you can try:
- Verify that the correct Microsoft account appears under Settings > Accounts > Email & accounts and that the same account is listed in the Microsoft Store profile.
- Check whether the game appears in your Microsoft Store Library under owned purchases and launch it from there instead of the game shortcut.
- If you use multiple PCs, review the devices associated with your Microsoft account and remove any devices that are no longer in use before testing again.
If the game is still shown as owned but continues to generate the same error, the next best step would be to contact Microsoft Support so they can review the purchase entitlement associated with your account and confirm that the license is correctly recognized.
I hope this helps point you in the right direction. Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.
