Download and install

Windows installer and first launch.

Game will not start Exit Code 1 and other launch errors.
  1. Write down the exact error code or message. Exit Code 1 alone does not identify the cause.
  2. Check that your Minecraft version and mod loader match your modded setup.
  3. If the game still closes, send support the error and superlauncher.log from %APPDATA%\SuperLauncher\logs.
Out of memory Java Heap Space and OutOfMemoryError.
  1. Check how much memory is assigned to the game in your setup settings.
  2. For Java Heap Space, increase assigned memory gradually. Do not assign all of your PC’s memory.
  3. If the error persists, send support the exact text from the launch log.
Graphics error OpenGL / GLFW 65542.
  1. Update your graphics driver from the manufacturer’s official site and restart your PC.
  2. Try launching again without shaders and recently added graphics mods.
  3. If GLFW 65542 continues, send support the error and your graphics card model.
