The Digital Picture Postcard™ was designed to play on most all computers. The most common problem is the slide show will play back slowly, and require more time to down load off the CD-ROM drive on some older computers. If you find that the presentation plays but is very slow, I would recommend asking a friend if you might try it on their computer. The performance of the presentation is improved on newer desktop computers. Laptop computers will play the Digital Picture Postcard™ but the graphics, music and sound effects will not be as clear. Desktop computers have better displays and speaker. Back To Returns Page
