Re: Octave 4 installer doesn't detect JRE at install time

[Will]

I did reboot the computer. For a bit more information, I also just tried 
setting the JAVA_HOME environment variable to  C:/Program 
Files/Java/jre1.8.0_45, and this actually got rid of the warning message 
when running the installer, but when testing things out when running 
Octave, commands like 'javaclasspath' and  's = javaObject 
("java.lang.String", "Hello OctaveString")' as recommended in the wiki, 
they return "error: unable to find Java Runtime Environment: 
software\javasoft\java runtime environment::Currentversion".
