Downloading and Installing

You can always find the latest up to date links to download the latest version of ATLauncher from the downloads page.


ATLauncher is super simple to install on Windows. We provide a simple and easy to use installer that you can get setup and running within minutes. If you haven’t already, download the Windows Setup from the downloads page, then simply double click it to run the setup process.

You may get issues with downloading through Edge, or when trying to open the installer, saying it could harm your device or is unsafe. All our code is completely open source, so you can verify every bit of code we run on your computer.

Click here if downloading through Edge and seeing a warning about it harming your device.

If you downloaded it through the Edge browser, you may get warned that it was blocked from downloading and could harm your device. ATLauncher is safe, and Edge/Windows can be overly protective. In order to bypass this, simply click the ”…” and choose Keep.

Then click “Show more” and then “Keep anyway”. This will let the download complete.

On the next screen you can choose if you want to install Java or not. ATLauncher requires Java on your computer in order to run itself and Minecraft. By checking this box it will install a version of Java that works with the launcher and for Minecraft. If you already have Java installed on your computer, you can uncheck this box, but it’s best to leave it checked:
