Adobe Acrobat and Reader Update Problem - 01/25/12 03:39 PM
Since I have found a solution to my immediate problem this is technically not a request for technical help so I am lodging it here rather than in the Mac OS X Applications forum.
There is a thread in the Applications forum reporting problems with Adobe CS5 and files erroneously reporting The disk copy was changed since you last opened it. I have been encountering what may be a related problem attempting to update both Adobe Acrobat X and Adobe Reader from version 10.1.1 to 10.1.2. The updaters continually report they were unable to complete the update because the files had been modified and suggesting they be reinstalled from the original disc. Checking Adobe's web site simply repeated the advice of reinstalling the product and I was reluctant to pay for technical support.
I was eventually able to update Adobe Reader by downloading the full Reader 10.1.2 and installing it rather than the updater, but since I could not download a full version of Acrobat 10.1.2 I was stymied. I reinstalled Acrobat X from the original copy, ran the updater and it reported it was unable to complete the update because the files had been modified. Finally I ran the Acrobat Uninstaller and totally removed all traces of Acrobat from the system, reinstalled from the original disc, and only then would the updater run.
I have no idea what was causing the 10.1.2 updater to fail, but the fact it happened on both Acrobat and Reader seems suspicious to me. I will be looking long and hard at alternative solutions the next time Acrobat comes up for an upgrade.
