I had read that there would be an update for Adobe Reader today. This evening I opened the Adobe Reader interface, went to Help > Check for Updates, an update to version 9.3.1 was shown, and I updated. After the update, I verified through Help > About Adobe Reader 9 that the new version was showing, just as I always do.
I opened the Firefox 3.6 browser and noticed that the plug-in version was still showing version 9.3.0.148, the previous version. I then examined the installation folder where I have Adobe Reader installed in the Program Files folder and to my surprise there were no new file dates. On further examination, I discovered that the file versions for the major files (AcroRd32.exe, etc.) still showed version 9.3.0.148. In the entire folder and sub-folders only one file (AcroForm.api) in the plug-ins sub-folder has the new version 9.3.1 number. I rebooted my system; no change. I downloaded the installer, saved it to my hard drive, closed my browser, ran the install. I was given the choice of Repairing or Removing version 9.3.1; I chose Repair, and it appeared to go through an install/re-check of the files. Still no changes in dates or files versions except for the one file in the plug-ins sub-folder, AcroForm.api.
Can anyone explain this obvious discrepancy? Why a 26MB download to change a 10MB file? Any information or explanation will be appreceiated.
My system: P4, XP SP3 fully updated, 1.5G RAM, updated Flash Player last week to 10.0.45.2, Shockwave Player 11.5.6.606, everything up-to-date.
