Great page lifted from the Adobe Website:
The Adobe Digital Publishing Suite is available for InDesign CS5, InDesign CS5.5, and InDesign CS6. To install the full set of tools for InDesign CS6, run the DPS Desktop Tools installer by choosing Help > Updates in InDesign. To install the full set of digital publishing tools for InDesign CS5/CS5.5, two separate installations are required. Install both the Folio Producer tools and the Folio Builder panel.
AIR 2.x is required to run AIR applications such as the Desktop Viewer. The most current version of AIR is available at http://get.adobe.com/air/.
If you experience problems installing the tools, see Installation Issues.
Installing the DPS Desktop Tools (InDesign CS6)
- In InDesign, choose Help > Updates, and update DPS Desktop Tools.
- The DPS Desktop Tools installer installs the Folio Overlays panel, the Folio Builder panel, a required InDesign plugin, and the Desktop Viewer.
Note: Whenever a new version is released, it can take a few days for the newest installer to be included in the InDesign Updates installer. During this period, you can update the DPS Desktop Tools by clicking the link in the Folio Builder panel or by downloading the most current installer from the DPS Dashboard or the Adobe Downloads page.
Installing the Folio Producer tools and Folio Builder panel (InDesign CS5/CS5.5)
Exit InDesign. Then:
Install the DPS Tools.
Install the Folio Builder panel.
Installing the Adobe Content Viewer on a mobile device
If you have an iPad, an Android device, or a PlayBook, install the most current version of the Adobe Content Viewer from the store. In the store, search for “Content Viewer.”
Updating the DPS Desktop Tools (InDesign CS6)
Whenever a new set of tools is released, choose Help > Updates in InDesign and update the DPS Desktop Tools. If you need to create folios that are compatible with an earlier viewer (v20 or later), you can use the Folio Builder panel to target that viewer version.
Updating the Folio Builder panel and/or the authoring tools (InDesign CS5/CS5.5)
The Digital Publishing Suite tools are updated frequently. Whenever there is a new release, the Folio Producer Service is updated on the web. There is a separate installer for the Folio Builder panel so that you can update the panel without updating your tools. Whenever Adobe updates the web client, update the Folio Builder panel to make sure that the web client and the Folio Builder panel remain in sync.
Note that updating the Folio Builder panel does not update your authoring tools.
The Folio Builder panel updates are available on the Adobe Downloads pages:
You also have the option of updating the authoring tools when a new version is released. When you update the authoring tools, any folio you publish is not compatible with any pre-v20 viewer version. For v20 viewer versions and later, update the authoring tools, and you can specify the viewer version when you create a folio. See Create a folio.
With InDesign CS5/CS5.5, you may need to revert to a previous set of Folio Producer tools to be compatible with an older custom viewer (v19 or earlier). Uninstall the Folio Producer tools, and then download and install the appropriate version. Older tools are available on these pages:
To see a table that matches tool versions to viewer versions, see the Please update your app tech note.
