Resolving Error 0X803F8001 on Minecraft for Windows PCs

The Minecraft Launcher error 0x803f8001 usually occurs when users attempt to open the launcher or download and install it from Microsoft Store.

Several factors may contribute to this; there could be an issue with your Microsoft Store account, you are not signed in with the account that has a Minecraft license, Microsoft Store cache, launcher installation, or the Microsoft Store itself could be corrupted. Likewise, not updating your operating system for a long time can cause the issue.

If this error prevents you from running the game, here are some fixes you can try.

1. Ensure You’re Signed Into the Right Microsoft Account

Make sure you are logged into the Microsoft Store with the same account that has the Minecraft license. Here is how to check that:

1. Type**”Microsoft Store”** into Windows Search and open the app.
2. Click on theprofile icon in the top-right corner of the screen.
3. See the details of the account that is currently logged in.
4. If you are signed in with a different account, clickSign out to sign out of the Microsoft account. Then, sign in with the right account.
   

If you’re already logged into the Microsoft Store with the correct account, sign out once and sign back in again. This will feasibly resolve any account synchronization issues and glitches.

2. Run the Windows Store Apps Troubleshooter

As the Microsoft Launcher and Microsoft Store are both UWP (Universal Windows Platform) apps, the Windows Store Apps troubleshooter might provide a solution. The Windows Store Apps troubleshooter can fix various app issues, which fortunately includes this 0x803f8001 error.

Here is how to launch the troubleshooter:

1. Launch Settings to view theSystem tab.
2. Click theTroubleshoot andOther trouble-shooters navigation options in Settings.
3. Scroll down to Windows Store Apps, and click theRun button for that troubleshooter.
   
4. The troubleshooter will open and scan for app issues. Apply any potential resolutions it suggests.
   

3. Ensure the Windows Time and Date Is Correct

One of the leading causes of Microsoft Store errors is incorrect time and date settings. When you launch a game, it connects to the game servers remotely. If the time and date aren’t configured correctly, this can lead to miscommunication between the host and server, which can lead to the error in question.

An independent advisor on the Microsoft Community forum also recommends selecting the correct time and date format to avoid facing such issues. They recommend using the ISO 8601 time and date format, which starts with the year and continues with the month, day, hour, minutes, seconds, and milliseconds.

Keeping that in mind, check the time and date in the bottom-right corner of your screen. If the date and time are correct but not in the format described above, refer to our guide on how to change the date and time format in Windows and select the appropriate one.
