>What DLL (and any other files) need to be on a user pc. I want to put the needed files on a zip cartridge.

Take a look at the FAQ here on What runtime files do I include with the App or something like that. There are a couple files that you may not need depending on what your app does, but I use them all to be safe.

You should really use some Install app though, files do need to be registered, and its easier for the user.
