Question

I have 3 projects in my solution that I want to deploy. Is there a nice and quick way of using Visual Studio’s setup projects to deploy all three apps using one MSI and letting the user decide which apps he wants to install during the install process?

I have setup projects for the 3 individual apps, I also have an overarching setup project that has the output of those other three projects. Am I on the right track or is there a better way?

I think you probably want merge modules. Accrding to MSDN:

A merge module is a standard feature of Microsoft Windows Installer that packages components together with any related files, resources, registry entries, and setup logic. You can use merge modules to install components that multiple applications share. You cannot install merge modules directly. You must merge them into deployment projects.

In your case, each application would be a merge module and you would need to provide some UI to select which applications you would like to install. You could modify one of the default page templates to do that.
