Symptoms or Error

When launching a Citrix XenApp application after upgrading to a different version of Citrix Receiver, the following error might occur: 
Citrix Receiver Error:

"This version of Citrix Receiver does not support selected encryption. Please contact your administrator. Error 1046: The Virtual Driver is not loaded.”

However, the applications run without any errors at the second attempt. This issue only occurs when using the Citrix Receiver; whereas using earlier versions of ICA client or XenApp Plug-in does not display this error.


This issue has been resolved. The fix was first introduced with a special release of Receiver 3.4 CU2. This update had also been included with the 4.x version release of Receiver for Windows on June 26, 2013.

Note: If you are still experiencing this error, you may have a corrupt Receiver installation. Try the following tool if a fresh installation is required:

Problem Cause

A call blocked during startup is causing a timeout which results in the error.
