How To Download & Install

To download the ATLauncher you need to select the correct version. If you are running Windows then you should select the 'Windows (.exe)' button. If you are running a Mac, Linux or prefer to use the jar file, then you should select the 'Linux/Mac/Others (.jar)' button.

Put the exe/jar file in its own folder somewhere on your computer such as on your desktop or documents folder, making triple sure you place it in it's a new blank folder.

Once downloaded and placed somewhere it's as simple as opening it like you do any other application. Once the ATLauncher is open you can then go to the 'Accounts' tab and enter in your Minecraft Username/Email and Password combination to add your account and start playing packs.

To play a pack just simply navigate to the 'Packs' tab and click 'New Instance' on any of the packs you want to play. Optionally give it a name and pick a version to install and click Install and the process will run through and by the end you will have a working instance which you can play in the 'Instances' tab.

Using The Jar Or Exe?

Make sure you save the download to a new folder somewhere. Don't just place this on your desktop or run it from your downloads folder, it should be run from a folder of it's own.

Do you have Java installed?

In order to use ATLauncher, you must have Java installed on your system. If you don't have Java installed, you can download and install Java 8 from here.
