citrix receiver error 1046 the virtual driver is not loaded

On one of our Windows 7 pc's we get the error: This version of Citrix Receiver does not support selected encryption. Please contact your administrator. (error 1046: the virtual driver is not loaded)

The error happend over night, no idea what the cause is.
I tried reinstalling the Citrix receiver (, but same result. Even used the Citrix ReceiverCleanupUtility to remove all registry settings concerned and installing again: same result. Tried the latest version of the Citrix Receiver: same result.

Funny thing is: I have about 40 pc's all running the exact same configuration and Citrix receiver version, but we (luckily) only have this problem on one pc.

I also tried a system restore to an image from a couple of days ago when everything worked, just to rule out any windows update errors: same result.

Any ideas how to fix this? (other than a complete reinstall of the pc)

did you tried to change the registry as mentioned in this discussion http://discussions.citrix.com/topic/329481-the-virtual-driver-is-not-loaded/page-2
Frank RuttenSystem Administrator


Yes, but on my pc the value mentioned in that discussion [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\ICA 3.0]

is empty, so I cannot remove anything from it.
Thanks for your reply.
