Right, but that doesn't include registering programs, help files, and 
extensions. It's pretty hard to write a good Windows program without doing 
those things.

Janus/Ada used to be that way, but people can't figure it out. These days, 
they expect do-everything installers. I'd surely prefer to spend my time on 
other things, but you can't claim customers are always wrong and expect to 
have any customers...
