How can I install an application multiple times?

[Houdini]

I'm trying to create an MSI install that simply wraps our current installer setup program. The idea is to have it simply run our installer silently to install the application, so we can have a MSI installer and our normal installer, without duplicating any effort.

For this to work properly, though, I need the MSI to NOT "register the application" with Windows, as our normal installer will already be doing this. I figured out how to remove the control panel entry, but after I install using the MSI and I try to reinstall, the MSI says it was already installed. How can I stop the Setup Factory installer from registering itself with Windows, so I can run the install multiple times?

I do not know of a way to do that. It sort of defeats the purpose of MSI.
