I am attempting to figure out how to do what AdvancedInstaller has done with their own installer. That is, if the user has already installed v3.1.1 and is attempting to install v3.4.3, I want a screen in the installer to come up and ask what the user wants to do: Remove the previous version and replace it with the new one or keep the old one around and install the new one. How do I accomplish this?
