Overview

Minecraft is an incredible experience for many, and for many more, it has served as a foundation for far more – With the growing community of modders, Minecraft has seen a giant number of mods and modpacks to tailor the experience to the player’s needs. Whether it’s a set of mods focused on ‘teching up’ through the ages of steam, coal, and fusion, or a modpack dedicated to expanding Minecraft’s adventure more than ever before. Feed The Beast has been a group at the core of many of the most popular modpacks in Minecraft history, including Direwolf, Skyfactory and Infinity Evolved. At Apex we host the latest versions of just about every pack they’ve released, recently, however, FTB had decided to end their partnership with CurseForge, and instead, use their own launcher exclusively for the latest updates of their modpacks.

Still, that doesn’t stop the FTB Launcher from being a convincing choice. With its direct support for all From The Beast modpacks, including modpack-specific RAM settings, it remains the easiest way to play and keep up to date with FTB packs, even when they were still partnered with Twitch. So in this guide, we will look at how to install the FTB launcher and get started with your favorite Feed The Beast modpack!

Common Issues

Insufficient Memory allocated to Java
Usually this isn’t as much of a problem with FTB packs as the launcher tries to use the recommended size, however if the issue happens, you can fix it by doing this:

1. Click the three dots when hovering over your modpack in the FTB Launcher
2. Click on the Settings tab for the pack
3. Change the “Instance Memory” slider. For example, if it was on 4GB, try raising it to 6GB.

It’s important to not raise it much more than 50% of your total system memory. For example, if you have 8GB of RAM, you shouldn’t raise it any further than 4GB.

The app says “Issue connecting to backend… Please wait or relaunch” when starting from the taskbar (Windows)
This error happens if you try pinning the shortcut for the FTB Launcher to your taskbar while it is open. To fix the error:

1. Unpin the current shortcut.
2. Open your start menu, and search “FTBapp”.
3. Right-click on the best match, then click “Pin to Taskbar”.
