ClickOnce Update Problem

[C# Programming]

Hi All,

I created a simple application in C# that displays a message when a button is clicked. I want this app. to be updated from a network drive, the same network drive that it was published from using ClickOnce.

In the Publish --> Updates window of the apps properties, it's set up so updates are checked "before the application starts".
After a modification is made to the application and I re-publish it the updated files are sent out to the users machine along with an updated very of the setup.exe file.
However, when the user starts the application from the start menu they aren't informed that an update is available and the old version of the application is ran.
The start.exe file can be ran and the new version installed then, but this isn't what I want the user to have to do. Shouldn't the user be informaed of the updated version when the app is ran?

Any ideas would be greatly appreciated.

Thanks,
Mel
