# Java ## Installing Java Before you start, you will need to make sure you have the correct version of Java installed. One of the most common problems that people encounter when running a server is having 32-bit Java or having the incorrect version of Java for the given Minecraft version. All Enigmatica modpacks require 64-bit Java, and the specific version required is listed below. ### Windows * Go to [Adoptium.net](https://adoptium.net). * For **Minecraft 1.16** or earlier: Select **Temurin 8** (LTS) as the version. * For **Minecraft 1.17** or later: Select **Temurin 17** (LTS) as the version. * Select Latest release if you are downloading it from a 64-bit Windows computer. * Otherwise, select Other platforms and change Operating System to Windows and Architecture to x64. ### Ubuntu or Debian Linux * For **Minecraft 1.16** or earlier: Run this command from the command line: `sudo apt-get install openjdk-8-jre`. * For **Minecraft 1.17** or later: Run this command from the command line: `sudo apt-get install openjdk-17-jre`. Note that the package might have a different name depending on the version of the distribution you are running, so you should get familiar with the *apt* command and how to manage packages on your system. ### Fedora, RHEL, or CentOS Linux * For **Minecraft 1.16** or earlier: Run this command from the command line: `su -c "yum install java-1.8.0-openjdk"` * For **Minecraft 1.17** or later: Run this command from the command line: * `su -c "yum install java-1.17.0-openjdk"` Note that the package might have a different name depending on the version of the distribution you are running, so you should get familiar with the *yum* command and how to manage packages on your system. ### Mac * Go to [Adoptium.net](https://adoptium.net). * For **Minecraft 1.16** or earlier: Select **Temurin 8** (LTS) as the version. * For **Minecraft 1.17** or later: Select **Temurin 17** (LTS) as the version. * Select Latest release if you are downloading it from a 64-bit macOS computer. * Otherwise, select Other platforms and change Operating System to macOS and Architecture to x64. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
