OS X Startup Error: The main class could not be loaded

During startup on Apple systems if you see an error dialog that lists an initialization error or a class not found, it is best to go clean out the attempted install and start fresh.
To do this, open Finder and in the top menu click Go and select Go to folder from the list.  A dialog window will open with a field to type a path into.  Please enter:
and click OK/Open.  When the new Finder window opens select the entire contents of the folder and send to Trash.
Open the launch.dmg again and re-execute the lab specific .app file listed when the file unpacks.  It should then install and start correctly.  If there is still a failure, copy the .app file into your Applications folder and try to execute it from there.
