Troubleshooting a Kojo Installation
If you are having trouble installing Kojo, it is most likely because of a problem with Java on your machine. Fix this by getting the latest version of Java from the Java download page. At the time of this writing, that version is Java 8. Kojo does not yet run with Java 9 or later.
