Generally you should use Java with the same architecture as your CPU. There are different version requirements for different Minecraft versions. If you don't know which one and how to get it, read on. After you installed the correct version make sure to select it.

Windows

Eclipse Temurin: https://adoptium.net/temurin/releases/?os=windows&arch=x64&package=jre&version=21

 

Minecraft 1.17 until 1.20.4 (Java 17)

Pick the JRE versions and make sure to match the architecture with your system, usually x64 (64-bit)

For least amount of issues, choose .pkg download.

Minecraft 1.16 and older (Java 8)

• Go to https://www.java.com/en/download/manual.jsp
• Download the Mac OS X package. Make sure to download the x64 as ARM is currently not supported.
• Install it.

 

Linux

temurin-21-jdk

Setting up Java in MultiMC

• In MultiMC, set it up using the Auto detect feature in the main settings - see Java-settings for details.
• See Increasing Java's memory allocation for more details about Java memory settings.

Set Instance Java Installation

Go to Edit Instance -> Settings -> Java -> Java Installation.

My Java Installation doesn't appear on the list, what do I do?

Try refreshing the list. If that fails, you'll need to locate the Java executable yourself - within the root Java directory this is ./bin/java on Unix systems, and .\bin\javaw.exe on Windows.
