Unable to launch weka 3.8 or weka 3.9.6 "Package manager" on Windows 10

Have tried both and uninstalled Java 8 then re-install later version of java but to no avail. I know this is new user error?

Error in console:

Environment variable 'JAVA_OPTS' does not exist!
Environment variable 'CLASSPATH' does not exist!
