Adobe Reader cannot open Protected Mode due to a problem with your system configuration.

Issue

If you are starting Adobe Reader and have Protected Mode enabled, you may encounter the following dialog:

“Adobe Reader cannot open in Protected Mode due to a problem with your system configuration. Would you like to open Adobe Reader with Protected Mode disabled?”

Reason

This dialog appears when protected mode cannot be started due to environmental settings on your computer.  It can occur due to anti-virus software conflicts, and/or conflicts with accessibility tools or smart card software and drivers.

Troubleshooting

1. Unsupported configurations:

  • Installing Reader on a mapped network drive.
  • Running Reader on WinXP when the OS is installed in a public folder.
  • Launching Reader in XP-compatible mode on Vista and Win7.
  • Launching Reader by right clicking AcroRd32.exe and choosing Run As.
  • Using PKCS#11 smart cards in signature workflows. Some cards can work in the presence of custom protected mode policies. For a workaround, see below.
  • Collaborating in real time using the Collaborate Live feature.
  • Certain configurations of anti-virus software that have not yet white-listed AcroRd32.exe. See Anti-virus software conflicts below.
  • JS-invoked processes: Launching a process through JavaScript is not allowed with Protected Mode enabled.

2. Antivirus software conflicts:

By default, Adobe Reader X runs in Protected Mode. In certain situations Reader experiences compatibility issues with anti-virus software when that software intercepts some system calls for the Reader sandbox. In these cases, Reader could fail to open or crash after displaying an incompatible-configuration dialog.

For example, Protected Mode is known to be incompatible with:

  • Some Symantec Endpoint Protection configurations. Adobe recommends that users update to Symantec Endpoint Protection 11.0 RU6 MP2 or higher.
  • McAfee VirusScan Enterprise for certain actions in Reader. Known actions include the following:
    • Clicking Help or a Weblink from an embedded Flash widget such as a Portfolio navigator (Fixed 10.1).
    • Launching of some IME tools. Note: Disabling Buffer Overflow Protection can provide a workaround for many McAfee users.
    • Reader sometimes removes a user’s cached credentials when signing out of Adobe.com which could be an issue for a multiuser machine. Fixed 10.1.2 with MVE 8.8.

Adobe is working with anti-virus companies to resolve these problems.

3. Accessibility

For XP only: Accessibility features sometimes doesn’t work. The Read Out Loud feature is unsupported. Therefore, screen readers such as JAWS, Windows Eyes, and Windows Narrator aren’t always able to read PDF content. Much of the Accessibility menus involving things like quick check, change Reading options are removed. Keyboard navigation is not implemented.

Note: When a screen reader like JAWS, Window-Eyes, or Narrator is running when Reader is started for the first time on XP, Protected Mode is disabled. On Vista and Windows 7, screen readers do work normally.

4. P11 smart card workaround

The installation of some smart cards doesn’t work for Reader X users when in Protected Mode. Because Protected Mode sandboxes certain processes that make system calls, smart card installation can fail or result in the “unsupported configuration” dialog appearing. However, a simple workaround is available. Install the smart card software with Protected Mode turned off as follows:

  • Disable Protected Mode by going to Edit > Preferences > General and deselecting Enable Protected Mode at startup
  • Restart Reader
  • Install the smart card software according to the provider’s instructions
  • Re-enable Protected Mode
  • Restart Reader

5. Windows Permissions

You should also check the permissions on the Adobe Reader installation folder.  Protected mode will only work on Windows when the group “BuiltIn\Users” has the following permissions on the Reader installation folder (for a default installation C:\Program Files (x86)\Adobe\Reader 10.0):

  • Read & execute
  • List folder contents
  • Read

CQ: design and preview mode toolbar not visible

Issue

If you are using the sidekick on an author instance of CQ, you may notice that the toolbar at the bottom which includes the design and preview mode buttons, is not visible or available.

Reason

The functionality in the sidekick is determined by the ACLs (Access-Control-Lists) defined in the CQ server.  If you do not have the appropriate privileges then functionality may be hidden in your sidekick.  Sometimes the sidekick may become unstable if you add faulty components to the page, or after you have installed some packages that may have overwritten required objects in your application, breaking some dependencies.

Solution

You should first try to clear your browser cache, and then reload the page from WCM console to refresh the sidekick.

You should also ensure you have the correct privileges to access the appropriate design in /etc/designs.  This can be changed by an administrator on the Users tab in the siteadmin console.  If the privileges appear to be correct, then try to disable them, save, and then re-enable them and save.  The sidekick should now display the toolbar again as expected.

CQ5.5: how to start the server in debug mode

Issue

In CQ5.4 you could start the server in debug mode using the [CQ_HOME]/crx-quickstart/server/server.bat file.  The server folder is no longer there in CQ5.5 on Windows.

Solution

To start the server in debug mode you can edit the [CQ_HOME]/crx-quickstart/bin/start.bat file and add the same debug parameters from a server.bat in an existing CQ5.4 installation, or you can use the command line below:

java -Xmx512m -Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=30303,suspend=n -jar cq-author-4502.jar

Notes

You may notice that the “Attach Debugger” entry in the CRXDE menu is still disabled even after starting the server in debug mode.  You should analyse the console output on server startup to check for issues related to heap/memory problems which may result in a new process being forked.  The debug options used to start the parent JVM are not passed on to the forked process by default.

You can resolve this by adding more heap to the JVM, and/or by specifying the -nofork command line option to prevent forking.  You can also force the forked process to use the parent JVM parameters by specifying the -forkargs [<arg>…] command line option.

You can find more information on the options mentioned above, and other server startup options under the following link:
