Unsupported major.minor version 52.0

52.0 = Java 8.

Seems like you are using Java 7.

I used the link from the B4J installation steps
https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

is it possible the errors caused from 32-bit..?

Thank you Erel for your point (=Java 7)

I found that JAVA_HOME pointed to another location (changed by another app with embedded java7 files)
so the solution was very simple, then
