Overview

The Minecraft community has grown a lot over the years, but one of the biggest parts of this community has always been the modding community with a constantly growing list of diverse modpacks that continue to push the limits of what can be done. In the pursuit of making modpacks easier to play than ever, a number of launchers have appeared in the community, one of the most extensive of these is MultiMC.
While MultiMC doesn’t let you download and install a pack in one click, it has a much broader range of features that give you fine control over your experience while still being easy to use with any modpack. MultiMC will take any modpack you can throw at it and do all the work to get you playing as fast as possible. In this guide, we will look at how you can install MultiMC and use it to play your favorite modpacks.

Minecraft runs on Java, so it’s important to ensure you have the latest version installed, you can always check on Windows by searching and clicking on ‘About Java’ in the Start Menu. (aboutjava.png in drive) If you’re unable to check, you can still always try installing the latest version on the Java Website.

Common Issues

Insufficient Memory allocated to Java
Modpacks can be very large, as mentioned earlier in the guide, it was suggested to raise your memory during the installation process. If you have spare memory available on your computer, you can always add more this way:

  1. Click “Settings” at the top, or if you only want to modify the memory for one modpack, right-click it and select “Edit Instance” then “Settings”
  2. Select the Java tab, then simply increase the Maximum Memory Allocation. If you are editing a modpack, you’ll have to check the Memory checkbox first.
  3. Click close and run your modpack!

 
Can’t login
This most commonly occurs when a user changes their username. To fix this, click on “Profiles”, “Manage accounts”, then select your existing account and remove it, then re-add your account with your Email and Password.

The second most common reason is simply that Mojang’s servers are down. You can check this by looking at the indicator at the bottom of MultiMC for “Auth”. If it’s red, then it’s likely their servers are offline and you will have to wait.
