Recently I have seen a couple of cases where the Citrix Receiver 3 client produces the following error when trying to launch a published application:

Error number 2320<br /> Citrix online plug-in Configuration Manager: No value could be found for (ClientHostedApps) that satisfies all lockdown requirements. The lockdown requirements in force may be conflicting.

The most salient part of the error message is in between the parenthesis. In the error message above, ClientHostedApps is a registry value that resides in two locations: HKLM\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Control (on 64-bit systems: HKLM\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Control) and HKCU\SOFTWARE\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Control

The fix couldn’t be simpler. Just delete the value for ClientHostedApps in these locations, refresh your applications in Receiver, and you should be able to launch published applications.
