Do I need to install Minecraft Launcher in order to use Minecraft Java?

Solution 1:

The Minecraft Launcher license is not currently available for your account. Make sure you're signed in to the Microsoft Store and try again. We include an error code if you need it: 0x803F8001.

Minecraft has recently moved to a new launcher. Previously, you'd download an installer .exe from the minecraft.net website, you'd run this installer file, and the Minecraft Launcher will be installed as an application on your Windows 10 machine.

Now, the Launcher used to begin playing Minecraft: Java Edition is a purchasable app from the Microsoft Store. It's free, but you may not be able to get it if you did not buy Minecraft: Java Edition on the Minecraft website.

Now, you bought a copy of Minecraft: Java Edition using a Microsoft account. Before you will be able to download the new Launcher app, you must sign into your Microsoft account within the Microsoft Store application. Type ms-windows-store://signin into your browser's address bar. It will activate the Microsoft Store login page.
