Adobe Reader Protected Mode

When you try to open a pdf file with Adobe Reader show the following message:

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

• Open with Protected Mode disabled
• Always open with Protected Mode disabled
• Do not open with Protected Mode disabled

Adobe Reader Protected Mode

Solution 1:
If you choose one of the first two options, the file opens, with the third no.

Solution 2:
To change your system configuration, launch Adobe Reader

click Edit menu then select Preferences…
or
use shortcut Ctrl+K

Inside General category uncheck “Enable Protected Mode at startup” on the bottom of the page.
Then click Yes in the confirm alert window

Adobe Reader
You have to chosen to turn off Reader’s protected mode. In order for these changes to take effect, you would have to manually restart the application.

Are you sure you want to continue?

Adobe Reader Protected Mode Turn Off Alert

and then click OK on bottom of the page to close Preferences window.
Close Adobe Reader.

Note:
If you use the Microsoft Application Virtualization (App-V) Softgrid Client or Citrix Receiver, the Acrobat Reader is an application different from your local installation. You have to change the configuration here rather that in your local installation. I suggest you to open the file using the first option then change system configuration from this window.

Citrix – “Error number 2320 Citrix Receiver Configuration Manager: No value could be found for (ClientHostedApps) that satisfies all lockdown requirements. The lockdown requirements in force may be conflicting.”

Citrix Receiver

Citrix Receiver client produces the following error when trying to launch a published application:

Error number 2320
Citrix Receiver Configuration Manager: No value could be found for (ClientHostedApps) that satisfies all lockdown requirements. The lockdown requirements in force may be conflicting.

Solution:

The most salient part of the error message is in between the parenthesis: ClientHostedApps is a registry value.

Open the registry editor
Click on the start button and then on run type regedit and click OK.

Navigate in the registry
on 32-bit systems:
HKEY_LOCAL_MACHINE\\SOFTWARE\\Citrix\\ICA Client\\Engine\\Lockdown Profiles\\All Regions\\Lockdown\\Virtual Channels\\Control

on 64-bit systems:
HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\Citrix\\ICA Client\\Engine\\Lockdown Profiles\\All Regions\\Lockdown\\Virtual Channels\\Control

Right-click ClientHostedApps and select Delete.

Now you can launch your published application.

My configuration: Windows 7 Home Premium Service Pack 1 and Receiver 3.0 For Web Access.
