Question

Minecraft used to work, now it wont launch no matter what I do.

Titus Pummer 0

I have this gaming laptop that is windows that I bought minecraft on. It used to work just fine, bedrock and Java. However, I tried it again recently and it wont launch no matter what. No matter where I launch it from it always says "something went wrong launching your game. Error code: 0x800711c7". I have updated everything, Uninstalled and installed everything, and I have done everything else under the sun but it just wont work. This is my laptop that is not under any school system as well. Any help? Thank you!

Hello Titus Pummer,

I understand how frustrating this is, especially after Minecraft previously worked and you have already reinstalled everything.

Please check whether Windows Security blocked part of Minecraft:

Open Windows Security > Virus & threat protection > Protection history.
Look for Minecraft.Windows.exe or GameLaunchHelper.exe.
If either was blocked, open the entry and select Actions > Allow on device.
Restart the PC and try launching Minecraft again.

Hey there, sorry for the late reply. I just tried this and there was nothing under protection history. I tried minecraft again and there was the same problem.

Hello Titus Pummer,

Thank you for checking. Since Protection history is empty, there is no blocked Minecraft item available to restore, so please try repairing the shared Microsoft Store and Xbox components that the Minecraft Launcher depends on.

Sign out of the Minecraft Launcher, Xbox app, and Microsoft Store.

Press Windows + R, enter wsreset.exe, and press Enter.

Restart the computer, then sign back into all three apps using the same Microsoft account that owns Minecraft.

Open Settings > Apps > Installed apps.

For Gaming Services, Xbox, and Minecraft Launcher, open Advanced options, select Repair, and test Minecraft. If the error remains, return to the same page and select Reset.

Restart the computer and try launching both Minecraft for Windows and Java Edition again.

If error 0x800711c7 still appears, please confirm:

Whether both Java Edition and Minecraft for Windows show the same error when opened separately.

Whether any third-party antivirus is installed.

The code still appears, however, I could not repair Gaming Services or Xbox because it said that "The app was still running" even when I was not running it. I tried to press terminate on both and it did nothing. I opened task manager to end both apps and it said that "This process is not valid". When trying to open Java, it forces me to go to the launcher which puts out the code. When I try to do "Minecraft for windows" it puts out this statement. "Files\WindowsApps\Microsoft.MinecraftUWP_1.26.3301.0_x64__8wekybsd8bbwe\WERHandler.dll is either not disigned to run on Windows or it contains an error. Try installing the program again using the original instillation media or contact your system administrator or the software vendor for support. Error status 0xc0e90002." I only have a microsoft antivirus. Additionally, a couple random games on steam have also stopped working for entierely different error reasons. I want to focus on Minecraft but maybe that hints towards something more wrong with the PC.

Hello Titus Pummer,

The WERHandler.dll Bad Image error and the problems affecting other games indicate that we should check Windows itself before reinstalling Minecraft again.

Please open Command Prompt as administrator and run these commands one at a time:

DISM.exe /Online /Cleanup-Image /RestoreHealth

sfc /scannow

Restart the computer after both commands complete, then test Minecraft and one affected Steam game.

After restarting, also check whether Repair or Reset now works for Xbox, Gaming Services, and Minecraft Launcher under Settings > Apps > Installed apps > Advanced options.

Please share the exact final result from both commands if the problem continues.

Hello there,

Still nothing yet. When I ran the DISM command it showed this:

Deployment Image Servicing and Management tool

Version: 10.0.26100.8972

Image Version: 10.0.26200.8973

When I ran the sfc command nothing showed up. I restarted and tried Minecraft and one steam game again with no changes. Also, Gaming Services and Xbox are still refusing to be Repaired.

Hello Titus Pummer,

Thank you for testing that. At this point, please try a Windows repair reinstall:

Go to Settings > System > Recovery.

Select Reinstall now under Fix problems using Windows Update.

Restart afterward, then test Minecraft and one affected Steam game.

If that option is missing, the fallback is an in-place reinstall using Microsoft’s Windows installation media guide, selecting the option to keep personal files and apps.

Hello,

I apologize for the late reply but I have recently started college and have been very busy. I did try the Windows repair reinstall as directed, yet I am still having the same issues with minecraft and steam. I have been debating trading in my computer since it is pretty much new except for that one issue. Any advice?

Thank you!
