Updating to Adoptium
First, I must specify two things. Today's date is 21-January-2024, and our current supported Java version(s) are specified here.
This guide is written to assist one in switching to the recommended version when using Adoptium.
- Uninstall Your Current Java Install: Uninstall your current Java installation first, or you will have problems (multiple players have found this out the hard way and reported it to us).
- Reboot Your Machine: This ensures that all changes take effect properly.
- Go to Adoptium Archive: Adoptium Archive
Go to and make sure the dropdown menu (highlighted yellow and underlined in red) says version 11 - LTS is selected.
Find your OS and unless you are planning to code for the projects you only need the JRE version. The JDK (Java Development Kit) isn't required and just has extra files.
Make sure to download the 64-bit version (underlined in Red for Windows) for your OS. If you are on an old version of Windows (XP and before) you'll need to 32 bit Java and its likely the MILESTONE won't run. You'll need to stay with the old 0.48.0 Stable.
Note:
If using the 0.49.7-MILESTONE you **MUST** use **Java 11**.
If using 0.49.11-Development releases or later.
Support has been added for Java 17, which is **ONLY** available for 0.49.11 or higher versions.
- Download for Your OS: Select and download the version appropriate for your operating system.
- Run the Installer: Download and execute the installer file.
-
Install Options (Critical Step):
When you get to the install options, you need to change the bottom 2 (Set JAVA_HOME variable, and JavaSoft (Oracle) registration keys) to be installed. Click the drop-down and set to "Will be installed on local hard drive".
When done, it should look like this:
- Complete Installation: Click next to finish the install.
- Reboot Again: Reboot your machine to finalize the installation.
If this doesn't work, return to step 1, and redo all steps and double check STEP 6!
You should now have the recommended Java version installed.
