I tried to install Adobe reader 9 it kept on asking for installation package for Adobe reader 7.1 then I downloaded 8.1 the same error. I had 7.08 setup files. When I tried to install 7.08 it kept on saying I have better product installed. I am not sure where the the Adobe reader 7.1 is or where to find it. I searched on Adobe.com but don't seem to find it. Where can find 7.1 version setup files?
I have found with Adobe/Macromedia as well as Apple Quicktime products that upgrades as well as installs work best when the work is done in the same profile as the install. e.g. you have a normal profile elevated to admin rights, but installed in the administrator account, some uninstalls and upgrades just will not function.
I have also found the Revo free uninstaller helpful in these cases
