After searching around on other forums and help sites, I found the answer @ http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_programs/acrobat-8-or-9 -with-windows-7-64bit-printing/99f812d3-d025-44f4-bba2-5a483ce1e730. The part I did was downloaded the update to 8.1, and it worked perfectly after that.
Glad it worked for you. That was even the case for XP - 64 bit. On the other hand, you might expect problems to crop up since AA8 is not certified for Win 7. As long as it works you are in good shape. Sharing the problems and solutions are helpful for those still running AA8 with Win 7.
