MBi Posted April 10, 2018 Share Posted April 10, 2018 Hello, More and more users complain that Receiver is not working anymore and display this error : "This version of Citrix Receiver does not support selected encryption." It seems that the issue occurs after and upgrad from 4.9 LTSR to 4.9.2000.21 LTSR. Receiver is upgraded from SCCM using these parameters : CitrixReceiver.exe /silent /includeSSON /ENABLE_SSON=Yes /EnableCEIP=false Any help? Thanks. Link to comment
1 asbjoslashrn thom Posted October 22, 2018 Share Posted October 22, 2018 We had alot of issues with this last year on one of our client images. EDIT: none of the steps in https://support.citrix.com/article/CTX133536 worked and this would always be a problem on freshly installed images. After using procmon and debugview we narrowed it down to one of the virtual channel dlls ( think it was vdtw30n.dll ), which aborted because of waiting too long. Workaround that worked: HKLM -> Software -> Citrix -> ICA Client -> Engine -> Configuration -> Advanced -> Modules -> ICA 3.0 ConnectTTYDelay = 1000 When changing this to ~2000 the problem was gone on all Receiver client versions. According to Citrix it is safe , but this key is just increasing the time in which a connection should expire or time out. This usually happen when its waiting for network and not getting response, so you would want to run network diagnotics on your network. The problem has since gone away with newer versions of windows/changes to end client image. 1 Link to comment
0 Ankur Mittal Posted April 26, 2018 Share Posted April 26, 2018 Hi, Would it be possible to share CDF traces for all the modules? Follow https://support.citrix.com/article/CTX111961 to capture logs. Link to comment

0 AA 2913 Posted October 1, 2018 Share Posted October 1, 2018 I have updated our users citrix receiver from 4.3 to 4.9 LTSR and still the user gets the same error message "This version of Citrix Receiver does not support selected encryption. Please contact your administrator". What could be wrong? I also did the registry changes as mentioned in Solution 2 and 3 from the above link but still no luck. https://support.citrix.com/article/CTX133536 Link to comment
0 Sven GOOSSENS Posted November 7, 2019 Share Posted November 7, 2019 The ConnectTTYDelay = 1000 was the solution in my case. Thanks! Link to comment
