Hello TL:
Please excuse my delay in getting back to you. I can't begin to thank you enough for your help. Incidentally, I posted the problem on the Adobe forum and did not receive even one reply!!

I may have gone too far in removing everything with the word "adobe" from my computer, but I developed a bad attitude that morning. I then re-installed Reader 8, and the installation worked. So far, all the attachments are opening.

Thanks, again. I sincerely appreciate all that you've done.

George
