I personally use Inno Setup:

If you get the starter pack which includes ISTool, making an installer is pretty easy. It is also extensible--for instance, I'm going to use the Inno Key Generator tool to make a registration system.

And you don't need the Extensions that IKG says you need, they're a part of the latest Inno Setup version. This method is more complicated but it'll do until RastaMan releases the Registration Code version of FPSPack.
