What is Java Runtime Environment (JRE)?

Java Runtime Environment (JRE) is a software package offering the needed components for running Java applications. Being developed in Java, Minecraft requires the JRE to be installed on your PC to function properly.

When you encounter the “Unable to Locate Java Runtime” error, Minecraft cannot find the necessary JRE files.
