I am having trouble configuring a visual studio setup project for an
application so that it will automatically override any existing installation
of the application. At this point the user has to remove the previous
installation before installing the new app. If I was using Windows Installer
in the raw I believe I could set it up to do this but from within the Visual
Studio setup project is this possible?

Thanks,
Steve

Try playing around with the GUIDs. When you increase the version number it
asks you whether you want to change this and that GUID as well. Maybe if you
leave one or both of them it recognizes it's an update.
