How to Fix a JNI Error in Minecraft


Minecraft Java is a popular edition of Minecraft that allows players to customize their game with various mods. However, this edition is not without its glitches and errors. One common error that Minecraft Java players may encounter is the JNI error, which displays the message “A JNI error has occurred, please check your installation and try again.” This guide aims to provide tips for fixing the JNI error in Minecraft.

Why Does a JNI Error Occur in Minecraft?

A JNI (Java Native Interface) error in Minecraft usually occurs when there is an outdated version of Java installed on the computer. Older versions of Minecraft were compatible with older versions of Java, but the latest update requires Java to be up-to-date. Another possible cause of the JNI error is a corrupted or incorrectly installed version of Java.

How to Fix a JNI Error in Minecraft:

To fix a JNI error in Minecraft, follow the steps below:

1. Download and Install a New Version of Java:

The first solution is to download and install the latest version of Java. Here are the steps to do so:

– Visit the official Java website and select the appropriate download for your operating system (Windows, Linux, or Mac).
– Choose the latest Windows version and click on the x64 installer to begin the download.
– Run the Java installation and select the default installation path (C:\Program Files\Java).
– After the installation is complete, open File Explorer (Win + E keys) and check if a new folder is created in the given path.
– Right-click on the path and copy the address (C:\Program Files\Java\jdk-20\bin\).
– Open the Minecraft launcher and select the Java edition of the game.
– Under the Installations tab, choose the Java version you installed.
– Click the three dots next to the Play button and select Edit.
– Expand More Options and paste the address from Step 5 into the Java Executable box, adding “javaw.exe” at the end (C:\Program Files\Java\jdk-20\bin\javaw.exe).
– Save the changes and launch Minecraft to check if the JNI error is resolved.

2. Delete the Environmental Variable of Java:

Another potential solution is to delete the environmental variable related to Java. However, the exact steps to do this are not provided in the content.

3. Perform a Clean Boot:

Performing a clean boot can help identify external applications that may be causing conflicts with Minecraft. Here are the general steps to follow:

– Perform a system search for “System Configuration” and open the corresponding result.
– Go to the Services tab and check the option to hide all Microsoft services.
– Click on “Disable All” to disable all non-Microsoft services.
– Go to the Startup tab and click on “Open Task Manager.”
– Disable each startup item one by one, restarting the computer after each disable.
– After identifying the problematic process, remove it from the Startup tab.
– Launch Minecraft to see if the JNI error persists.

4. Uninstall the Previous Version of Java:

It is recommended to uninstall any previous versions of Java from the system to avoid potential conflicts. This can be done through the Control Panel.


In conclusion, if you are experiencing a JNI error while playing Minecraft Java, it is advised to update Java to the latest version, ensure there are no conflicting system path variables related to Java, and try troubleshooting the issue through a clean boot. Removing any previous versions of Java can also help resolve the error. If further assistance is needed, the content suggests contacting the support team for prompt help.
