I suggest going to www.*********** and downloading his program that works with Inno Setup. It's called Inno Script, and you just direct it to your vbp file, and it creates a script that includes all of the needed files for Inno Setup to compile the installation progam (which comes as a single .exe).
He also has an option called the Auto Updater, which will bring the computer's files up to specs, so that the user doesn't have to install anything from Windows Update (as is often required while installing a P & D installation with the cab files.)

There is the Application Deployment forum for these types of questios.
