How To Download & Install

To download ATLauncher simply select the download below for your operating system.

For Windows users, the setup is the recommended way to install ATLauncher as it will make sure that you have the correct Java versions installed to make the process of playing Minecraft easy without any hassles. But if you are an advanced user, you can deselect that option and use the Java already on your system. For a step by step guide on how to install ATLauncher on windows see this page.

If using the Windows Portable or Jar download, be sure to place it in its own folder somewhere on your computer. ATLauncher will run out of that folder, so make sure you're not running it from your Downloads folder.

To get started you'll need to do two things. First you'll need to add your account, then you can create an instance to start playing Minecraft within minutes.

If you have any issues then please feel free to join our Discord and ask for help in the support channels.
