PDF is Adobe Corporation's Portable Document Format (PDF). PDF files may be downloaded or viewed on-screen. To read PDF files, you need the Adobe Reader. If you don't have it, click on the icon below and download it for free from Adobe's site. Please note that it may take a while to download the file from Adobe depending on the speed of your modem. The file you will download from Adobe is a self-executable file. It must be run first for it to install itself. Please note the name of the folder/directory to which you are downloading so you can run the file later in order to allow it to install itself. When you have downloaded the Acrobat Reader from Adobe's site and have run the file so it can install itself, you should be able to view PDF documents.
