This is regarding the issue with Citrix Receiver, when launching the Citrix application through a URL, we were getting an error “Citrix online plug-in Configuration Manager: No value could be found for (Allowhotkey) that satisfies all lockdown requirements. The lockdown requirements in force may be conflicting.” After reinstalling and installing Citrix Receiver many times there was still no fix for the issue. It wasn’t until I dug deeper into the registry of my desktop. Follow these steps and you will be back to work in no time!

The following Steps will resolve this issue.
<ol>
	<li>Deleting the following entries under the registry location
<ol>
	<li>HKLM\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Control</li>
</ol>
</li>
	<li>Search for (AllowHotKey)
<ol>
	<li>Delete “AllowHotKey”</li>
</ol>
</li>
	<li>Log back into Citrix
<ol>
	<li>Another error should pop up mentioning “URLRedirection”</li>
	<li>Search within the registry for “URLRedirection”</li>
	<li>Delete “URLRedirection”</li>
</ol>
</li>
	<li>Log into Citrix again
<ol>
	<li>Another similar error should populate mentioning “ClientHostedApps”</li>
	<li>Search within the registry for “ClientHostedApps”</li>
	<li>Delete “ClientHostedApps”</li>
</ol>
</li>
	<li>Log into Citrix once more, and you should be good to go.</li>
</ol>
