As described in the topic header,
Can CCleaner be made to install just 1 instance of the application
and
Can there be either an automatic update or manual (button) to update of the uninstall list?
I often use CCleaner to uninstall an older application and then install the most recent application
Flash Player being the most common. For whatever reason I find a clean install of Flash Player
functions better than an upgraded version of the player.
