I am having and issue with Citrix Receiver on one of the system I manage. I get the error message "This version of Citrix Receiver does not support the selected encryption. Please contact your administrator." I found several topics suggesting corrupted registry entries and to use the clean-up utility. I have done all that. I finally resorted to re-imaging the system and starting from scratch. This worked for about and hour until the user restarted the machine. I have several other systems with the exact same setup that don't have this issue. Where is this coming from? Has anyone resolved this issue?
