Hello, thank you for your response. I am sure that I have the right version 
of java installed. When I typed in the java home command, it responded with 
%JAVA_HOME%, not with what yours said. How am I able to check if it is a 
problem with java home or path, and how do I fix it if it is? I also tried 
to install robocode using the command prompt and it did not work.
