How do you do that?

How do I get Aristois to update Fabric Loader from 0.12.8 to 0.12.12? My mods require version 0.12.12, and Aristois cannot update Fabric Loader. What to do and how? Is it possible to do it manually?

It's already on 0.12.12. Since you have a cracked launcher it will not update for you.

You must delete the libraries, redownload, and reinstall the entire mod. I cannot help more than this unless you use the official launcher.
