FeatureLockdown (Lockable Settings)

Preferences under FeatureLockdown require administrator privileges to change. Setting these preferences locks the user interface so that the end user cannot change product functionality. The settings on this page include those which do not have a similar setting in user preferences. Do not assume that because a preference is not documented here that it is not lockable. Choose the Lockable tab at the top of the page for a complete list of lockable settings.

Note: On Macintosh, while preference names for unlocked settings do not use Hungarian notation, all locked settings (with the exception of attachment settings) DO USE Hungarian notation. That is, prepend the preference name with its data type ("b" for boolean, "i" for integer, and so on). On Mac, the locked incarnation of a setting uses the same name as if it resides on Windows. For configuration and deployment details, refer to the Enterprise Administration Guide.


This preference category contains the following subfeature(s):

Services-Master Switches (DC)

These settings apply only to DC products. By default, Adobe online services are tightly integrated with the user interface so that users can leverage them in enterprise workflows. Adobe's services are rapidly evolving and allow your organization to increase its efficiency with zero infrastructure and management costs.

It is not required, but in general, admins deploy the Continuous track with services enabled. In some environments, the Classic track is deployed without services. It is not required, but in general, admins deploy the Continuous track with services enabled. In some environments, the Classic track is deployed without services.

PDF Ownership

When Reader X and Acrobat X are installed on the same machine or earlier versions of Acrobat already exist, you can choose which viewer is the default for PDF files. While Acrobat is the more capable, feature rich application, Reader X has a built in Protected Mode which is more secure (For security details, see the Application Security Guide).

This feature is a Adobe PDF handler-only feature: It does not enable switching to and from non-Adobe products and may or may not change the handling of other Acrobat supported formats; for example, it changes FDF and XDP, but not XFA or PDX.

Administrators interested in security may want to make Reader the default PDF viewer. Version X products will be able to switch between any product type and version back to 9.x.

For more information, see the PDF Ownership knowledge base article.

Summary Disables the abilitinky to change the specified default handler (PDF viewer).
Details Note that UI configuration does not set any key in HKCU. Instead, changing the setting via the UI invokes the installer which sets the key in HKLM. The default application behavior varies depending on what is installed. A value of 1 disables the user's ability to change the default handler. Possible values include:
  • 0 (or null): Allow the user to change the default viewer.
  • 1: Don't allow the user to change the default viewer.

Flash

Adobe Reader and Acrobat stopped shipping with a dedicated Flash player in version 9.5.1, . Since then, rendering Flash content in a PDF requires that a Flash Player already reside on users machine. This strategy simplifies Acrobat and Reader deployments by reducing the number of future required updates should a security issue arise.

Opening a PDF that requires Flash when Flash is not present on the machine results in a dialog prompt to download and install the latest Flash player. To pre-install Flash, go here:

Note: Flash de-coupling is not available in Safari for 9.5.1. Otherwise, Acrobat 9.x products require the Flash Player browser plug-in (Safari and Firefox) version 11.2 or higher. Flash Player 11.2 stopped supporting Windows 2000 and Mac OS lower than 10.6. Therefore, users need at least Windows XP and Mac OS 10.6.x to view Flash content in a PDF.
