force Maintenance mode if installed?

We would like to have a Basic MSI installer that will check if our app is installed and then show the maintenance dialog if it is.

We can use installScript or some other medium to check for the presence of the app, but once that is known what do we do to get the maintenance dialog to come up in a basic msi?

Thanks for any ideas!

I'm a little confused. The standard behavior of an MSI is to show the maintenance dialog if that version of the MSI is already installed. Are you talking about showing the maintenance dialog if you're doing a major upgrade?
