One more point: you can set your registry values when your application runs for the first time. It's a common practice especially on UNIX and MacOS to generate configuration silently, when needed instead of focusing user's attention on that during installation. Other than that, installation is essentially copying. The proper place, file-type bindings, version checks etc can be done by the system automatically, again, without annoying the user (and the developer, too). And that's exactly what MacOS was doing since version 5 in 1980's. (Besides, Windows Registry is one of the main sources of complication).
