Marc,
After finding so many weirdnesses in my environment variables, I decided to make sure my fopub was still working...

IT WASN'T!!!

However,  I got it working again!
by 1) adding this bit to my PATH:

%JAVA_HOME%\bin

and 2) adding these environment variables:

JAVA_HOME : C:\Program Files (x86)\Java\jdk1.8.0_144

JDK_HOME  : %JAVA_HOME%

CLASSPATH : .;%JAVA_HOME%\lib;%JAVA_HOME%\jre\lib

So, I am constrained to ask: does your set of environment variables include stuff sorta like that? Especially, is CLASSPATH present and looking correct?
