>Now I'm confused. I was talking about a VFP7 merge module for Visual Studio Installer. Are you saying that the VFP7 merge module that ships with VFP7, which can be used with InstallShield, can also be used with Visual Studio Installer? My ignorance of installer technologies is showing, I guess.

Doesn't Visual Studio Installer use the Windows Installer technology? If so, then everything is compatible because InstallShield uses the same technology. It just supplies a nifty interface to it.
