Download the YL System User Utility
Download the installation file and run it. It will automatically install the program and run it. The initial first run may take up to a minute to display as it must download the necessary data files.
Download the ZIP file archive from the link above.
It is a rather large archive as I have to distribute a number of Java packages that are not normally installed on a users computer.
Make sure that you have some version of Java 1.8 installed. Open a Terminal (command line) window and at the prompt type java -version. If you do not get some build of 1.8, then you will need to update your Java before you do anything else.
Extract the archive into a folder of your choice under your HOME folder.
Open a terminal and CD into that folder you created. There is a file called ylissb.sh that is the bash script to run the program. You will need to make that executable. At the prompt type chmod 755 ylissb.sh
You can setup a desktop launcher to this file to launch it.
For the first run, just to make sure we don't get any exception errors, start it from the command line. Type ./ylissb.sh or java -jar YLISSB.jar
The first run will take 30 - 60 seconds to download all the necessary data files and setup the database.
