I'm stuck! Patch backup on hold! May-Day,May-Day!

It's a protection fix patch US NTSC. After I download it I open it with autoexec. I get a dos page saying autoexec finished. Now what? How do I extract the archive to the path of the image file? Do I do that in the dos prompt? What command do I use if so?
It sounded easy in the instructions from megagames on patching. I know the solution is somewhere right in front of my face. I'm just not getting the whole dos thing. I tried to get the ppf omatic and get the same kind of dos window.
