Go get some freeware like PrimoPDF, or an acrobat distiller license. The way in which you actually make a PDF file is to "print" to the format. I don't think there are any ways to actually "save" to PDF, but needless to say printing to PDF with acrobat, PDFFactory, or PrimoPDF will you get what you want.
