I've written some installers using Installshield and later the WiX toolset, and the typical application developer has no appreciation on how difficult it is. "Just copy over the binaries, it's not hard." Well, when your customer is an enterprise who wants to deploy your product hands-off onto five thousand machines, and expects a clean uninstall when they want it removed later - yes, it's that hard. Writing installers really is it's own sub-speciality in software development.
