I use dblock's dotnetinstaller to do exactly that (although my secondary MSI is more of a pre-requisite rather than being optional). http://dotnetinstaller.codeplex.com/
The way I could think of doing it using MSI only is with using an external cab to provide the files of the optional component & use a Feature Condition that detects the existence of the external cab & allows install of the optional Feature if the cab is found. That would require some effort to make it work reliably though.

Subject: Re: [WiX-users] Upgrade, Patch, or something else... Unfortunately, the Windows Installer doesn't provide any native support for that sort of "chained uninstall". You'd need an external program to manage it. On Mon, Nov 8, 2010 at 6:56 AM, John D. Marinuzzi <nu...@hypack.com> wrote: > Hello All, > > > > I have a question about how to implement something.
