Minecraft New Launcher Install Failed (0xUnknownAppInstall)

ShavinCroos · Sep 1, 2022

Hi all,

I'm trying to install Minecraft's new launcher in order to continue playing Minecraft as normal, as well as updating Minecraft itself. However, when I try to install the new launcher, the error shown below is returned to me:

I've tried restarting my PC, carrying out the sfc /scannow command, repairing and resetting the microsoft store, but none of these options worked for me.

I'm at a loss as to why the launcher won't install but just returns this error. If there's anything else that I could try and haven't done yet, I would be grateful if someone could let me know. Anyone who has experienced this particular error code are also welcome to comment on any solutions or methods they tried to resolve the issue.

:)

Hi ShavinCroos! My name is Ricardo an independent advisor ready to help you with this situation!

Have you tried installing the launcher directly from the Xbox app instead of downloading the launcher installer?

If not please log in the Microsoft store with the account that made the purchase of the gane and the same on the Xbox app, look for Minecraft launcher and try to install it, let us know if you find any issue and share a screenshot please

I'm on Windows 10. In addition to what's already listed, I have now backed up my files, deleted .minecraft, and downloaded the installer from minecraft.net again. Now I can't even install the mc launcher. I can download the installer. But when trying to use it, it tells me "Looks like something went wrong. We weren't able to install the app (0xUnknownAppInstall)."

Then I uninstalled Minecraft completely from Apps & features and restarted my PC. I still receive the same error when trying to use the installer from minecraft.net. In the Microsoft Store, it shows that I already own Minecraft. When I click the install button there, it's unresponsive.

When I try to install it from the Xbox app, I receive a new error code:1x00000001.

I'm unable to try other accounts at this point since I can't even install the game anymore.

Earlier the same day I tried to download the new minecraft launcher and I ran into the same problem, later that day I tried to see if it was everything I download so I attempted to see by installing three unrelated applications but all three of them failed to install and I haven't checked anything else yet but those three apps still fail to install

Hello,

By installer do you mean the Minecraft Launcher is not installing Java? Can you confirm that you are using the new launcher and not the old one? Uninstalling the Old Minecraft Unified Launcher – Home

Thank you,

I see. If that fails, try downloading the game via Minecraft launcher. You can download the launcher through the Microsoft Store app, Xbox app, and the Mojang website. After installing the launcher, log in with your Microsoft account and download Microsoft Dungeons.
