Wow.. this one was a pain. I found a Adobe KB article on this one. http://www.adobe.com/support/techdocs/330817.html The part that worked for me was: msiexec /p Ac705RDP_efgj.msp REINSTALLMODE=omus REINSTALL=ALL /qn They had a diffrent MSP file, but I changed it to the file I had and it worked with no UI (/qn switch). Hope this helps someone. I'd install the 7.05 full, but I just finished installing the 7.00 and fixing the people who had the full blown so it would use the full version and not the reader.
