You need Adobe Acrobat Writer to convert any file into a PDF file. Unless you can find a computer that has the software already installed, for example, your friend's or co-worker's computer, you'll have to fork it up and buy the software. OR, if you're feeling lucky and adventurous, find it on one of the file-sharing networks - I wouldn't recommend it (because of viruses and trojans and worms), but that's your last resort.How do you change a Word file into a pdf file?
look for an illegal copy of distiller (adobe TM)



Or I suggest openoffice (a GPL (freeware)) office suit capable of working and saving in MicrosoftTM Office and direct export to PDF
