MacでCCleanerを自動実行して終了させるAppleScript

tell application "/Applications/CCleaner.app" to activate

tell application "System Events"
	tell application process "CCleaner"
		click button "Run Cleaner" of window 1
	end tell
end tell

delay 5

tell application "CCleaner"
	quit
end tell

delayを入れないと実行前に終了してしまうので5秒ほど待っています。
