How to Fix a JNI Error Has Occurred in Minecraft

An old version of Java may be why the JNI error has occurred in Minecraft. To fix this issue, you’ll need to install the latest JDK (Java Development Kit). However, if the problem still occurs, there is a possible solution to address this problem as well. Here is a step-by-step guide to resolve the JNI error:

  1. Go to the official website for Java and find the latest version.

    Visit the Oracle website and download the latest Java installer to your computer. Be sure to install the correct version for your system (Linux, Mac, or Windows).Java installer for Windows

  2. Install Java.

    Once you download the latest Java installer, continue to press the ‘Next’ buttons on the Installation Wizard. Install the latest Java version

  3. Launch Minecraft.

    Now that you have successfully installed the latest Java version on your computer, it’s time to see if the problem still occurs. Open up Minecraft and check to see if the JNI error pops up.Minecraft Loading

  4. Open your Run dialog box.

    If the JNI error window is still present, your path variable of Java may be corrupted or broken. For Window users, Open your Run dialog box by either searching for it on your Start menu or pressing the ‘Window’ and ‘R’ keys together.
    Mac users will need to access their terminal by searching for it on the LaunchPad or the Search Icon on the top-right of the screen.

  5. Type in ‘sysdm.cpl‘ and hit ‘Enter.’

    This step will launch your System Properties to find the corrupted file.

  6. Go to the ‘Advanced’ tab and click the ‘Environment Variables.’

  7. Click and Edit ‘Path’ in the ‘System Variables’ section.

    Search through the ‘System Variables’ section in the ‘Environment Variables’ tab and click on ‘Path.’ You’ll need to edit this to delete the broken file. Path File
