To create and preview folios for InDesign CS5 and CS5.5, you run two different DPS installers — the Folio Producer tools and the Folio Builder panel. There is only one installer/updater for InDesign CS6, but I’ll get to that later.
Why two installers for InDesign CS5/CS5.5?
Two reasons. First, Adobe doesn’t want to force publishers to rebuild and resubmit their custom app whenever a new set of tools comes out every six or eight weeks. Updating the app should be optional. Second, when Adobe makes certain changes to the Folio Producer Service on the web, the Folio Builder panel needs to be updated to remain in sync with the web client. Publishers need to be able to update the Folio Builder panel without updating the Folio Producer tools.
Should I update when a new version of tools comes out?
That depends on whether you have created a custom viewer app and whether you’re still updating it. If you haven’t created a custom viewer app and submitted it to one of the stores, the situation is simple. Just install the most current versions of the tools, and you’re all set with the new and improved tools. (There is one exception to this guidance. In some instances, Adobe release the new tools before Apple has approved the newest version of the Adobe Content Viewer. If that’s the case, you might want to hold off on updating the tools until Apple approves the viewer.)
If you have submitted a custom viewer app to the store, it depends. You have two choices whenever a new set of tools comes out:
(1) Don’t update your custom viewer. Continue using the older set of tools. If prompted, update the Folio Builder panel. Updating the Folio Builder panel does not update the tools.
(2) Update your custom viewer and submit it to the store. Install both the new set of Folio Producer tools and the Folio Builder panel.
Until the new version of the custom viewer is approved and available, don’t create or edit any folios for that app. Otherwise, when your customers try to view a newer folio in an older viewer, they’ll be prompted to update their app. Although viewers are backward-compatible with previously created folios, folios usually cannot be viewed in earlier viewers. That’s new wine in old bottles. (Or is it old wine in new bottles?)
Where do I get the installers?
You can download these tools from the Adobe Downloads page, the DPS Dashboard, or the Installing digital publishing tools help topic.
How do I know which installers I used?
Here’s how to tell which tools are installed and which tools were used to create a folio.
To see which tools are installed, open the Folio Builder panel and choose “About” from the panel menu. Look at the last numbers. For example, 7.0.5.17 means you’re using the v17 tools.

To see which viewer version you’re using, open the folio in the viewer and tap the title. The first two numbers indicate the viewer version. For example, 2.2.0.13.34603 refers to the 2.2 version of the viewer.

Unfortunately, the viewer version doesn’t match the Folio Producer tools. Here’s how they match up:
v12 (tools) = 1.7 (viewer)
v13 = 1.8
v14 = 1.9
v15 = 1.9 (no change)
v16 = 1.9 (not available for iPad)
v17 = 1.10
v18 = 1.11
v19 = 1.12
v20 = 2.0
v21 = 2.1
v22 = 2.2
v23 = 2.3
v24 = 2.3 (no change)
v25 = 2.4
Starting with v21, it’s possible to specify the viewer version when creating the folio. This feature works only for v20 or later.
For additional details, see the “Please update your app” tech note.
Updating the DPS tools in InDesign CS6
In InDesign CS6, the DPS tools setup is more straightforward. There is only one installer/updater, which you can run by choosing Help > Updates in InDesign. When you select “DPS Desktop Tools,” you update both the DPS tools and the panel. When creating a folio, you can specify which version of the tools the folio is compatible with (v20 or later).
