The SlingCatcher is hardware not software. Are you looking for the SlingProjector (http://support.slingbox.com/go/dl-windows-projector-us) or the SlingSync (http://downloads.slingmedia.com/get/slingsync-win-us.html) to use with your SlingCatcher? Or are you looking for the Slingplayer Desktop client to watch your Slingbox?
