      "No JVM could be found on your system.

      Please define EXE4J_JAVA_HOME to point to an installed 32-bit JDK or JRE or download a JRE from www.java.com."

      Done the register java removal suggested on webpages

      Manually removed Java and Sun folder/libraries in program, program86 and program data systemfolders.
