Dataloader Error: Java Runtime (class file version 55.0), this version is up to 52.0

Java Runtime 52.0 -> Java 8

Java Runtime 55.0 -> Java 11 or new

So need install Java 11 or new to replace Java 8.

After installed java 11, do not forget to check you Environment Variables [JAVA_HOME].

Make sure JAVA_HOME is the new path to java 11 file.
