→Acrobat 9 as an administrative deployment
To make an administrative deployment, run msiexec /a path_to_msi.msi TRANSFORMS="path_to_your_language_id.mst" and choose where you want the administrative deployment to reside.
Then you run msiexec /a path_to_administrative_deployment/acropro.msi /p path_to_quarterly_update.mst msp for each of the quarterly updates. You might want to snapshot this deployment, before applying non-quarterly updates, so you will not have to redo the whole process on a new quarterly update.
You can use Adobe Customization Wizard (ACW) on the administrative install, and make a wpkg package that installs the administrative install, applying the mst made from ACW.
