launching non-scriptable application at a SPECIFIC PATH

for some reason i cant figure out how to launch an application from a specific path


	set PathToUpdater to ((path to the "dlib" from user domain as text) & "Application Support:Espionage:Espionage Update.app")
		log "try to launch"
		
		tell application "Finder"
			launch PathToUpdater
		end tell

and nothing happens…
any help would be much appreciated
