Are you trying to install the product multiple times, or allow the end user to run it multiple times? I believe Windows will not allow you to install the exact same package multiple times, so the first option may not be possible. When you launch the installer again, Windows recognizes it is already on the system and goes directly into maintenance mode.

MSI supports multiple instance. Here's an example of how to do it with a Basic MSI, the same should apply to InstallScript MSI.
