The recipients of your CD will need to have Acrobat Reader installed. While it is becoming more common place for it to be pre-installed on many computers, there are still many that may not have it. You can remedy this in one of two ways: 1. Include a Text File Named Readme.txt and tell the user to go to: http://www.adobe.com/products/acrobat/readstep2.html and download the software. To view these files you need the free Adobe Reader software which is available for Windows and Mac platforms at http://www.adobe.com/products/acrobat/readstep2.html. 2. Go to: http://www.adobe.com/products/acrobat/distribute.html and read how to get permission to redistribute the Adobe Reader Software with your CD. This involves among other things filling out an online form, and reading over the license agreement.
