Click-Once Deployment

Visual Studio 2005 Team Edition, C#

Couldn't exactly decide where to put this, hope this is okay. From what I have seen, in order to use click-once the application must be installed via a click-once installer. Even if everything has been setup for click-once, installing via the MSI seems to leave behind the auto-update bootstrap.

I understand that installing via click-once is comparable to running the app in a sandbox, ect ect. What I would like to do, is have the user install the application via MSI (so that I may make registry changes and the like... just for the sake of argument assume that I must install via MSI). But I would like to leverage the auto-update functionality of click-once. Is there any way to combine the two?

if you'll have a program that is simple enough that click once is good enough, then it should probably not make registry changes. Or you could try making the changes when the program runs the first time.
