I have received the following error on my Citrix Receiver when I tried to run the published application:
Error number 2320, Citrix Receiver Configuration Manager: No value could be found for (AllowHotkey) that satisfies all lockdown requirements. The lockdown requirements in force may be conflicting.
Citrix Receiver was normally working, so I can’t tell what has caused this behaviour.
I have tried to shutdown Citrix Receiver on my client machine and shutdown all other active Receiver processes, but without luck.
To solve this error a small registry change needs to be done.
Open registry editor from the Run prompt (regedit.msc)
Navigate to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions
In the right pane double click on the EnableLockdown key and modify value from 1 to 0
Close registry editor and try to start published application on Citrix.
