Where is the help application bundled? Alongside the main app in the
same directory, or inside the main app's application bundle itself?
Perhaps it's a path issue, i.e. 'open' can't find the app to open. If
so, you may need to do some work to get a full path to the help app,
then launch it (i.e., os.system('open -a /path/to/myapp.app') ).
