    Setup project - how to uninstall an old version of your project?

    I have a WinForms app with an MSI installer created using a VS.net 2003 setup project. When you run the MSI on a machine where it's already installed, it refuses to run saying the old version must be uninstalled first.

    Does anyone know how to get the MSI to automatically uninstall an old version if present, and replace it with the new one?

    There is a "remove previous version" option in the MSI Project properties. I never have used it, so I cannot be certain.

    I've only gotten that option to work a few times!
