All of our CD-ROM's currently include a copy of Adobe Acrobat Reader. Periodically, Adobe releases upgrades to the Reader program. These upgrades are available for free from Adobe. Though the Reader that comes with the CD-ROM's works just fine, some may wish to upgrade to a newer version of the Reader. To do so, simply click on the link below and it should take you to the Adobe website where you can proceed to download the latest version. Furthermore, if you own a Macintosh computer, you may visit the Adobe website as well and download a Macintosh compatible version of the Acrobat Reader.
