# Using MultiMC

Then, right click → Edit InstanceSettingsJava

• Java installation: Minecraft 1.7.10 requires java 8 (newer versions might not work)
If you don’t already have it installed, get it from here or use your package manager, if you’re using linux.
Pressing Auto-detect should show you a list of installed versions, where you need to pick the one starting with 1.8.0, otherwise
on windows the path is usually C:\Program Files\Java\jre1.8.0_X\bin\javaw.exe (where X is the version number)
and on linux/mac os the path should be something like /usr/lib/jvm/java-8-openjdk/jre/bin/java
• Memory: I recommend somewhere around 512MB minimum and 4096MB maximum
• Java arguments: These should work well:

1

-XX:+UseG1GC -Dsun.rmi.dgc.server.gcInterval=2147483646 -XX:+UnlockExperimentalVMOptions -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=51 -XX:G1HeapRegionSize=32M



# Using the official minecraft launcher

In minecraft launcher, press InstallationsNew installation

• Version: release 1.7.10
• Game directory: for this example I will call it ancient-wormies/ to avoid confusion, but feel free to use any name and any location.
• More options:
• Java executable: Minecraft 1.7.10 requires java 8 (newer versions might not work)
If you don’t already have it installed, get it from here or use your package manager, if you’re using linux.
on windows the path is usually C:\Program Files\Java\jre1.8.0_X\bin\javaw.exe (where X is the version number)
and on linux/mac os the path should be something like /usr/lib/jvm/java-8-openjdk/jre/bin/java
• JVM arguments:

1

-Xms512M -Xmx4G -XX:+UseG1GC -Dsun.rmi.dgc.server.gcInterval=2147483646 -XX:+UnlockExperimentalVMOptions -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=51 -XX:G1HeapRegionSize=32M



feel free to tweak -Xms (minimum allocated memory) and -Xmx (maximum allocated memory) according to the amount of RAM available

Start this installation once and let it load. Then, close the game.

Download Minecraft Forge for 1.7.10 here. Either of these buttons should work:

Open the downloaded installer, make sure that “Install client” is selected; leave the installation path as it is, unless you installed minecraft somewhere else (this is different from ancient-wormies/) and press Ok.

Once again, open the minecraft launcher’s Installations tab and choose the installation you created earlier. Change the version to release 1.7.10-Forge10.13.4.1614-1.7.10 and press Save.

Hover over your installation and on the right side press the Folder button. A file explorer should open.
Then, download the modpack here: Full extracted .zip Extract the .zip file’s contents into your installation folder. The structure should be something like this:


1
2
3
4
5
6

ancient-wormies/
├─ config/
├─ logs/
├─ mods/
├─ options.txt
└─ ...other files



Then, pick the installation in minecraft launcher’s main tab and start the game! If you see a loading screen with the forge logo, you probably did everything right!

And if something isn’t working right, feel free to ask me! Contact
