Install/Verify Java (Windows)

You will need Java installed if you want to:

  • run the current version of the Fabric Installer
  • use MultiMC
  • change the default “JAVA EXECUTABLE” to other than the bundled Java runtime in a Minecraft Launcher “Installation”

Minecraft 1.17 and higher uses Java 16. If you want to run MC 1.17 download Java 16, not Java 8.
