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
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.

  1. I created a new user account on the computer, logged into the citrix site, it installed a fresh copy of the software on the fresh user account and worked. I went to the registry and exported the HKey_Current_User/software/citrix folder then went back to the old account and deleted that folder from the registry and imported the working registry info. Then deleted the new user account.

  2. I too had this issue. I found that the registry setting also resides under HKCU\citrix\ica client\engine\lockdown profiles\all regions\lockdown\virtual channels\control. There was an entry for hostedapps, the value was false! I deleted the entry and then apps opened fine.

  3. Go to Regedit from RUN

    Under the following Folder need delete a Key with a Value of “FALSE”

    You can find the key in two places,HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE.
    Better get into the HKEY_CURRENT_USER folder section, thats were it worked for me :-)

    HKEY_CURRENT_USER/Software/Citrix/ICA Client/Engine/Lockdown Profiles/All Regions/Lockdown/
    Virtual Channels/Control/

    Here find a KEY with the Value set to “False”, select the key and delete the same.

    Now do a Applications referesh on your citrix icon,

    You are all set to get ur apps up and running!

    Again Thanks for the post which helped a lot.

    Gr8 Help…Thanks a Lok

  5. Thank you Thank you Thank you for this resolution! Citrix allows me to work from home a lot of the time so that I can spend time with my newborn. *kneels*

  6. I found this to work also but what I’d really like to know is what it happens? I’m in pilot phase and would not like this to occur on production release… Any ideas?

  7. I tried the registry fix (in both locations), then uninstalled Citrix Receiver, rebooted, and re-installed Citrix Receiver. Unfortunately, I still get the same error message. Any other ideas?

    • While logged in as the affected user, remove the “HKCU\SOFTWARE\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Control” key and it should work.

  9. I have this same problem on one of my clients computer and i did what was suggested in here. I deleted the ClientHostedApps wich was only under HKCU and not HKLM. After this i refreshed the Citrix site but now when i try to open the link nothing happens. Before it would give me the error, but now, nothing. Is there something i can do or did i do something wrong? Anyone else had this problem?

    Thnx

  10. Wow, I have been trying for day’s now, off and on to to get into two different Citrix accouts with no luck. I was ready to throw out a brand new computer. Not sure if this error is due to the new Internet Explorer or Windows 7 but who ever figured this out… :smile: Thank you!!! I researched another error where citrix receiver was timing me out on the second login after about 2 sec. I deleted it and only installed the basic plug me in and then i got this error and fixed it quickly and easily with your help. After days of research and reading other peoples blogs and etc. You are the best. Thanks again :wink:

  11. BTW, I am using Firefox now. I downloaded the new Internet Explorer and had issues on my old computer, getting into Citrix, so now I am a Firefox fan…. I am assuming the fix works on IE, but I haven’t tried it.
