How to Fix 'A JNI Error Has Occurred - Please Check Your Installation and Try Again' in Minecraft

If you're experiencing issues with launching Minecraft or your server (.jar) without Java 16 in version 1.17, you're not alone. Many players have reported encountering the error message 'A JNI error has occurred - please check your installation and try again,' which is often followed by a 'Java Exception has occurred' error.

The good news is that the problem lies with the Java version, rather than a faulty or missing version of the game itself. Minecraft has recently been updated to use Java 16 with its latest patch, which may be causing issues for players who are running older versions of Java.

One common workaround is to ensure that you have the correct Java version installed on your computer. To do this, simply download and install Java 16 from the official website. This should resolve any compatibility issues and allow you to launch the game without encountering the 'A JNI error has occurred' message.

Additionally, if you're using TLauncher to start the game, try launching it in a different way or using an alternative method to see if that resolves the issue. If none of these methods work, you may need to consider purchasing a licensed version of Reimage Reimage to repair any damaged system files on your computer.

By following these simple steps, you should be able to fix the 'A JNI error has occurred - please check your installation and try again' issue in Minecraft and get back to exploring the world of Caves & Cliffs.
