Software Deployment

I have managed to sign the driver correctly now, my next task is packaging it. Does anyone know where I can get freeware Installer software which will allow me to create custom actions and merge modules, however if it comes to it I will put everything in one package and forget the merge module for now.
I'v searched for options and the only thing iv have come up with is a shareware installer called Advanced Installer, which works but, it is a trial some displays dialogue when the package is created.
Thanks
Craig
