Has it really been 6 months since my last post?? Here's a new Quick Note, as always.
My company still uses Adobe Acrobat 9 Standard but for the past month I've been unable to auto-update my new installs. Whenever I've tried the built-in Help > Check For Updates it reports "No updates available." I think I've now found the reason, as well as a workaround.
The base install of Acrobat 9.0.0 includes their older updater which is located in C:\Program Files x86\Common\Adobe\Updater6. Inside that folder there are two digital certs, e.g. AdobeUpdate.cer, which are dated 4/16/2008. I suspect those certs just expired last month?
The workaround is to manually update Acrobat 9 until you get the newer AdobeARM updater which was included in Acrobat 9.2.0. Worst case you'll need to manually download and install all the following updates:
9.1.0 > 9.1.1 > 9.1.2 > 9.1.3 > 9.2.0
The downloads are located on this Adobe page:
There might be some shortcuts? For instance, some online discussions say you can skip directly from 9.1.0 to 9.2.0. Also, you might try copying the C:\Program Files x86\Common\Adobe\ARM folder from an updated PC to an un-updated, then run the AdobeARM.exe ?
