Welcome to the ATLauncher website. This is the main point of contact to download ATLauncher, get information about ATLauncher and the packs in it as well as get some help.
ATLauncher is a simple and easy to use Minecraft Launcher which contains 148 modpacks for you to choose from. We at ATLauncher do not make any of these packs which makes what we do very unique. We help others get modpacks out there and in the hands of the public.
So why not take a look at the different packs that are available or just download ATLauncher and give a try yourself. If you're still unsure about us, then visit our about page to get a list of features.
Dec 18, 2021 - Further update on security vulnerability in Minecraft
As a further news item on from the previous one around the Log4J exploit in Minecraft.
ATLauncher has just released version 126.96.36.199 which fully patches all Log4J versions for all instances which include the Log4J library as follows:
- Minecraft 1.7 to 1.11.2 now uses a patched version of Log4J (version 2.0-beta-9-fixed)
- Minecraft 1.12 and onwards uses an updated version of Log4J with the vulnerabilities fixed (version 2.16.0)
While the patches that Mojang applied to their own launcher, and were applied in our previous launcher updates will fix the issue, these fixes provide a complete fix to the issue and leave no doubt that there are any more issues going forward (at least for the issues that we know of today).
These libraries will automatically download and install themselves the next time you launch your instances, there's nothing you need to do. For servers, you will need to recreate them to get the latest versions downloaded and applied.
As we've always mentioned, you should also make sure you're using the latest Fabric/Forge version where possible.
Dec 10, 2021 - Security vulnerability in Minecraft
As you may or may not be aware, there was recently a security vulnerability exposed within Minecraft through the Log4J library that is included and used by Minecraft versions 1.7 and later.
Mojang have already released a fix for the issue.
ATLauncher has released 2 updates to also address this issue. The first was to introduce a command line argument to prevent the exploit from happening. This is only effective in 1.17 and above. The second update (188.8.131.52) to make sure that on launch of your instances, the latest manifest is downloaded from Mojang and their fix applied to your instance before launching.
To make sure you have the latest version of ATLauncher, make sure to restart the launcher or use the Update Data button in the bottom left of the launcher to get any new updates for the launcher.
The best solution to make sure you stay safe is to update any instances that have them available or if you're using a vanilla instance with Fabric or Forge, you can make sure to update your Fabric/Forge version to the latest.
It's also important to note that these fixes will only apply to instances. Any servers created and run through the launcher before the 13th of December may not be safe to run and you should and you should delete and remake them to be safe. Again the best thing is to make sure you keep your Fabric/Forge version up to date if you use it.
If you have any concerns or questions, please reach out in our Discord server.
Nov 7, 2021 - Update 184.108.40.206 - Technic and Xbox Game Pass Support
ATLauncher has just updated to version 220.127.116.11 which includes various bug fixes and tweaks, but brings in a couple notable new features.
First is Technic support. Now you can install and play modpacks from the Technic platform. This includes support for updating, taking backups as well as adding mods from sources like CurseForge and Modrinth easily from within the launcher.
While we've done our best to make sure most modpacks work as expected, if you notice any issues, please reach out in our Discord server.
We've also added in support for being able to login and play for people who have Xbox Game Pass. If you have Xbox Game Pass and want to login to ATLauncher, you'll need to make sure you login via the Minecraft Launcher once in order to setup your Minecraft profile before being able to login to ATLauncher.
Again, if you have any issues, please come to our Discord server.
Jan 9, 2021 - Update 18.104.22.168
Version 22.214.171.124 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.
Dec 16, 2020 - Microsoft accounts now supported
Update 126.96.36.199 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.
