In some Java installations on Windows it doesn't set up the .jar extension to run automatically from Windows Explorer. Jar files are Java archives and have all the classes in the program and a manifest file to tell which class to run.
To run RobotBuilder use the java command:
java -jar RobotBuilder.jar
Actually there will be a version number on RobotBuilder, so choose the actual file name from your installation.
