Error while starting the Skybot agent on an AIX box.

Could not find the main class: com.helpsystems.enterprise.peer.StartAgent.  Program will exit.

Solution:

Check the permission for the directory that the agent is installed in and the directory above it. 

Need to be root to run the following command:

chown Skybot -R /opt/skybot

This is the directory if Skybot is installed in the agent directory: /opt/skybot/agent
