I have a C# application that I'm trying to get to update automatically via ClickOnce. After publishing newer versions of software, I see the new versions in my publish folder, but when I open the application, it checks for updates, and does nothing (even though there are new files in the publish folder).

What do I need in place for updates to be made automatically?

Edit

What version of Visual Studio are you using? Visual Studio 2008

Are you deploying the upgrades to the same location as the old version? They are being published to the same location (not sure about deployed)

Is the installation URL the same? Have you incremented the version number? Yes

In the Updates dialog reached by clicking the Updates button in the Publish page, do you have "The application should check for updates" checked? Yes

Do you have "Before the application starts" selected? Yes

How are you deploying the files? Not sure

Are you copying them over to the file share or publishing the directly? Publishing directly
