Embed an exe into project and use the publish update option

[jokerfool]

I've built an application inside of vs which is then built using an installer. The installers job is to download and extract the files to the server.

I want to be able to take advantage of the publish update section inside of vs by having the installer file placed inside of a simple form, so when I run the setup it checks to see if there is an update from the installer (Has the filesize changed at all) and if so let the user know there is an update, if no update is found tell the form to run the exe from the target location and run.

is this possible?

Inside of the installer application is an updater application, the problem with the updater is that it reveals the download url of the file from the server, all it would take is one person to look, take the url and then no body has to pay for the download.

I've got the idea in my head just not sure how it rolls out, any advice please
