ClickOnce doesn't push updates, it pulls them. So you put the files on a server, and when they run their application, it checks for updates and installs them.
So if I'm understanding this, you have dll's and you want to provide them to a customer to provide them to a bunch of users via a ClickOnce application?
You would have to create the deployment, setting the urls for your customer, and have them put it on their server. Then when the users run the app, it will automatically pick up the updates.
