Using the sec2pdf script
For Windows, you need to visit activestate.com and download the latest version of ActivePerl (currently 5.8.4) to install on your machine. Once it's installed, run Perl Package Manager, which opens a terminal window, and type "install PDF::API2". When that's finished, you'll be able to open a fresh cmd window, cd to the directory containing the sec2pdf script and your data files, and run it as "perl sec2pdf [options]".
