when I try to run java-installer my computer is giving me java exception error
Any ideas?
java-installer requires Java 8, and will throw an exception on startup if you have an older JRE. The Java 8 requirement is stated here: http://wpilib.screenstepslive.com/s/4485/m/13809/l/288822-installing-java-8-on-the-roborio-using-the-frc-roborio-java-installer-java-only
