--------------------------------
Seems changing the environment variable is not helping in this case.
Is there way to tell SikuliX installer to refer the required java version installed(ie Java 1.8)?
Or any way out for installaion?

Removing other Java version will impact other application running on server.

Appreciate your advise.
