<p>I have received the following error on my Citrix Receiver when I tried to run the published application:</p>
<p><strong>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.</strong></p>

<p>Citrix Receiver was normally working, so I can&#8217;t tell what has caused this behaviour.</p>
<p>I have tried to shutdown Citrix Receiver on my client machine and shutdown all other active Receiver processes, but without luck.</p>
<p>To solve this error a small registry change needs to be done.</p>

<p>Open registry editor from the Run prompt (<strong>regedit.msc</strong>)</p>
<p>Navigate to the following key:</p>
<p><strong>HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions</strong></p>
<p>In the right pane double click on the <strong>EnableLockdown</strong> key and modify value from <strong>1</strong> to <strong>0</strong></p>
<p>Close registry editor and try to start published application on Citrix.</p>
