Hello, I've found that Apache Lenya supports both windows and linux, this could be an example and way to learn for me, hence I decided to consider how did they make it. Beside of other, they use Nullsoft Scriptable Install System( http://nsis.sourceforge.net), license here http://nsis.sourceforge.net/License. We could use it to generate user-friendly windows install package for Couch DB.
Thanks, Alex
