Deploying using Setup project with update functionality of ClickOnce

I want to deploy a wpf client appllication, I need to allow the user to choose a directory for the install, eg. c:\program files\myapp. Unable to do this with clickonce, I need to use a setup project to deploy my app. How can I have the same update functionality as a ClicOnce app in my setup pro开发者_StackOverflow社区ject? ie Have the app check an adddress for update, download only changed parts of the app, and patch the client application.
