That list of old versions is rather incomplete; also, it does not download from the Adobe Site.
Navigate the Adobe FTP site ftp://ftp.adobe.com/pub/adobe/reader/ to download any current or previous Reader version.
My Reader 9 worked OK until 15 Sep 2011 when Reader X was installed auto. Since then I cannot get to read any of the pdf on my house sale/purchase. A similar "update" from MS in Jan 2010 made Word lock up the computer (50% CPU) unless I started it from the command line! What is wrong with these big companies that they keep messing up our software? Or is it Google messing everyone up?
Greetings. I right-clicked Reader 9 and went to Restore Previous Versions. That worked for me. At the same time, I can imagine there a many solutions that would work depending on your exact set-up.
