Admin Guide (“http://www.adobe.com/devnet-docs/acrobatetk/tools/AdminGuide/aip.html) says:
- Do not create the AIP directly on the root drive (e.g. C:). Use TARGETDIR on the command line or the AIP user interface to specify a different install location.
- If you previously deployed using an AIP, then you must apply the successive patches using an AIP.
- Know when you can reuse AIPs and when you have to create a new one. For example, Acrobat 10.x quarterlies are cumulative and cannot be installed on top of each other.
- 11.x products do not require uninstalling existing products that were installed via an AIP. Update the product as described at http://www.adobe.com/devnet-docs/acrobatetk/tools/AdminGuide/gpo.html
The correct steps for AIP deployment are:
- Always first create AIP for 11.0.0 and preserve it.
- Apply 11.0.09 Q patch over AIP created above in (1).
- Uninstall 11.0.08 AIP deployed earlier or follow 9 Group Policy-Active Directory — Enterprise Administration Guide
- Reinstall 11.0.09 AIP created at step (2).
- Repeat steps (2-4) when new patch is released (make sure to follow correct patch application Order).
