1. Download the Fabric Installer

Download the .exe version of the Fabric Installer from the Fabric Website, by clicking on Download for Windows.

TIP

The .exe version for Windows does not require Java to be installed, because it uses the Java bundled with the official Minecraft Launcher.

2. Run the Fabric Installer

Close Minecraft and the Minecraft Launcher first before running the installer.

Once you open the installer, you should see a screen like this:

Make sure the new game version and Loader version are correct, then click Install to update Fabric.

IMPORTANT

Make sure to uncheck 'Create Profile' when running the installer!

3. Update Profile in the Minecraft Launcher

Once installation completes, open the Minecraft Launcher. Then go to the Installations tab. Find your Fabric profile and open its edit screen:

Replace the version with the new version of Fabric Loader you just installed, and press Save.

4. You're Done!

Once you've completed the steps you can go back to the Play tab, select the Fabric profile from the dropdown in the bottom left corner and press play!

If you encounter any issues whilst following this guide, you can ask for help in the Fabric Discord in the #player-support channel.
