I am trying to install spark client IM in Ubuntu 14.04 64 bit, but it throws error 

Could not find or load main class com.install4j.runtime.launcher.Launcher

I performed step 1 from this link https://www.thefanclub.co.za/how-to/how-setup-im-voip-server-using-openfire-ubuntu-1404 but it still shows same error.

Any Help will be appreciated.

This error is occurring because the hidden directory .install4j was not moved to /opt/spark/ after you have made the command: mv Spark/* /opt/spark/ by terminal in /tmp. Make the display of hidden files in /tmp/Spark. Inside the directory /tmp/Spark you must do the following command: 

mv .install4j/ /opt/spark/
