I am new to setup factory and am trying to figure out how to do conditional installation of product parts. What I want to do is have a program I write be shelled out by SF and return a status or set a registry entry and then based on this status do or don't do parts of the setup. This must happen during the install process as the program will determine how to proceed based on what it finds. I don't see a good way to do this... can anyone point me in the correct direction ?
