Tutorial - How to load the seed in Alpha
Make sure you're using Minecraft Java Edition, with 'Historical versions' enabled in the launcher, and choose version a1.0.16. This version doesn't support entering seeds, so you'll either have to use save file editing, or just use our already prepared world file:
This will generate a fresh version of the herobrine world, with you standing at the exact coordinates. Make sure to use the correct Minecraft version or it won't work.

Jan 9, 2021 - Update 3.4.2.0
Version 3.4.2.0 of ATLauncher has just been released.
This version contains many bug fixes, but also contains a few new features, and upgrades to existing features.
First we now support the installation of modpacks from the modpacks.ch platform (aka FTB modpacks). Alongside this we've added in a simple browser for searching and finding modpacks on CurseForge, making to process of adding packs from other platforms super easy.
Along with that, we've made updating and reinstalling packs installed from CurseForge possible. Now when an update is found for an installed pack from CurseForge, you will now get an alert when launching, and in the instances tab, when there is an update to install. If you don't see the option to update or reinstall an existing pack installed from CurseForge, you may need to install the pack again using for it to start to work.
Next we've added the ability to import packs exported from MultiMC. So if you have friends using MultiMC or a pack has the option to download a MultiMC formatted zip file, you can now import that into ATLauncher to play and use.
Lastly, we've added the ability to import packs made with ATLauncher (or CurseForge or MultiMC) with a url. So you can host your exported instance somewhere on the internet (such as dropbox) and simply give that url to your friends to put into the launcher, rather than sharing a zip file.
As always, if you have any issues, please reach out on our Discord.
Minecraft Version Changer provides a big list of Minecraft versions to choose from. It takes just seconds to change between versions. You can even generate a backup of your current jar file if you. The launcher supports all versions of Minecraft, from first Alpha to latest release, including Forge & Optifine from version 1.4.7 to latest. (Manual installation of Forge is supported as well). Minecraft Alpha free download - Minecraft Offline Files Installer, Minecraft Forge for Minecraft 1.12.2, Minecraft Version Changer, and many more programs.
Dec 16, 2020 - Microsoft accounts now supported
Update 3.4.1.0 for ATLauncher has just been released. This includes initial support for Microsoft accounts for Minecraft. Please note that you still need to own the Java edition of Minecraft and not the one in the Microsoft store.
While migrations haven't yet started for existing Mojang accounts, new purchases of Minecraft are required to use a Microsoft account.
These new Microsoft accounts are now supported in ATLauncher and you can continue to play even if you have one of the new Microsoft accounts.
Please be aware that this is an initial implementation, if you notice any issues or something goes wrong, please let us know on our Discord so we can fix them up.
Oct 31, 2020 - Update 3.4.0.0
Version 3.4.0.0 of ATLauncher has just released which includes many bug fixes as well as a couple new features.
First is the new Export/Import feature which allows you to export your Vanilla Minecraft With Fabric and Vanilla Minecraft With Forge modpacks that you create within the launcher and create a CurseForge/Twitch compatible zip file.
This allows you to then give that zip file to a friend and allow them to import it to ATLauncher as if it was a CurseForge modpack. You can also take this zip file, and import it into the Twitch client or submit it to CurseForge as a modpack.
Second new feature is better theming support and multiple new themes out of the box. ATLauncher now has a new look, including multiple different themes. While the look and feel is very similar, it's now more rounded, modern and consistent, with extra attention to detail put in to make sure screens are laid out correctly.
Lastly we've sped up the launcher so that it loads much quicker when opening it after the first time. This means you can get to playing even quicker than before.
If you find any issues with these new features, or have any feedback, please let us know in our Discord Server
Oct 22, 2020 - New Microsoft account migration
Today Mojang have announced that Java edition will require linking a Microsoft account in order to use in the future.
This change is going to affect ATLauncher and most other third party launchers for Minecraft.
Our advice right now is that if you use ATLauncher or any other third party launcher or program that requires logging into or authenticating with Minecraft, that you do not migrate your account until the programs you use give the all clear that they support the new Microsoft login system when it's in place.

Aug 8, 2019 - Help Translate ATLauncher
Minecraft Alpha 1.2.6 Servers
ATLauncher is written in English only, and through community translations, we're looking to increase the number of languages that ATLauncher has, so that people can choose to use the launcher in their native language.
All translations and languages added to the launcher, which are not the base English language, are all community driven, and anyone is free to contribute, if you choose to.
If you wish to help out with the translation effort, please visit our Crowdin page.
If you have any issues or questions, please let us know in our Discord server.
