===== Updating the Fabric loader for an existing Installation in the Minecraft Launcher ===== 

:!: Fabric Installer is for the Minecraft Launcher. If you are using another launcher, such as the CurseForge App, you need to use your //launcher// to change the Fabric Loader version of your instance.

Sometimes you may need to update the Fabric loader of an existing Installation because a mod requires a newer version of the Fabric loader. You may encounter an error similar to this one:

Run the installer:

Select the ''Client'' tab. Select the ''Minecraft Version'' and  the ''Loader Version''. Usually there is no need to change the loader version, the latest one will work in any Minecraft version.

The ''Select Install Location'' should point to the Minecraft Launcher data folder. 

**Uncheck ''Create Profile'', we do not want to create a new profile this time, just install an updated version of the Fabric loader.**

Click ''Install''

Close the "Succesfully installed" dialog box.
