property lngsyncPath : "/Applications/LNGoogleCalSync/"

		set shellOutput to do shell script lngsyncFilePath
		
		if shellOutput does not contain "Running Lotus Notes Google Calendar Sync in GUI mode..." then

	set myPath to (path to me as text)
	display alert "Application not found" message "Application could not be started from

because of error

" & errorMessage & "

--> Or check the AppleScript to set the correct 'appPath'" as critical buttons {"Exit", "Edit Script"} default button "Edit Script"
	set response to button returned of the result
	if response is "Edit Script" then try
		tell application "Script Editor" to open myPath
	end try
	return
end scriptError
