By total accident I was wandering around my C:\ directory today and found C:\Documents and Settings\UserName\Local Settings\Application Data\Adobe\Reader 9.0\Setup Files .
Those of you who have followed this thread will know that I had tried many, many ways to download and install Reader 9. I have no idea which attempt downloaded the files in that directory. I am SURE that it was not a matter of downloading one of the various installation (.exe) files reported here.
It probably was a path using GetPlus or Nossos. (Don't ask how I got there. Maybe some of you will recognize those names.)
I do remember one procedure that showed a "downloading" of installation files (rather than "processing") but without reporting where they were being downloaded. After unsuccessfully looking for Temp files (or files with the name "Adobe" or "Reader" added to the hard drive) that day, I gave up on that. But maybe (probably) that is the source of today's find.
When I looked into the "Setup Files" folder, I found six files.

abcpy.ini
AcroRead.msi
AIRShareInstaller.exe
Data1.cab
Setup.exe
setup.ini

SetUp.exe was labelled as suitable for "installation on a single PC". So I clicked on that.
And now, after a somewhat confusing but automatic installation, Reader 9 is installed on my PC.
Whoopee? No. So far, I feel Reader 8.1.2 was more flexible. But since all I really do with Reader is open .pdf files and read them (which 9 still seems to do) maybe this is progress.
I hope this is helpful information.
P.S. I have not yet installed Air. Should I?
