Deleting an empty Parent Dir on Uninstall

I've got code to recursively delete items from the Start Menu (if they're empty), but how do I delete a parent folder if it is now empty? For example, two apps are installed in c:\progra~1\MyComp\MyApp1 & c:\progra~1\MyComp\MyApp2 -> if I uninstall both MyApp1 & MyApp2, how do I delete the MyComp folder on the last uninstall?

just do a rmdir without any flags, it will fail if the dir is not empty
