How to convert to PDF file?

I am not sure how to convert FHMX file to PDF file and have no idea which software to install PDF converter in FHMX.

Should I install Postscript Printer Driver (http://www.adobe.com/products/printerdrivers/index.html) on Window XP in order to convert FHMX file to PDF file? I may not have Adobe Illustrator software to convert FHMX file to PDF file.

Appreciate any feedback. Thanks.
