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.
