Extremely simple script for installing the QuiltMC Loader for the (as of writing this) latest Minecraft when the .exe version doesn't work and you don't have your own version of Java installed
Just put it in the same folder as the Quilt Universal installer and rename the installer to quilt-installer.jar, then run install-quilt.cmd to install. It uses the built-in Java of Minecraft launcher, and therefore requires the Microsoft Store version of the launcher to work
