"This version of the XOG client only works with Java 8."
"The following actions can be taken to resolve the problem:
1> Install Java 8 JRE and set the JAVA_HOME and PATH environment variables accordingly.
2> If Java 8 is already installed on the system, please use the '-javaHome argument to specify the installation location"
I do have Java 8 JRE installed. Not sure specifying the JAVA_HOME path.
