Citrix Online Plug-in 12.3 Cumulative Update 3

Citrix has released a new version of their Online Plug-in (12.3.300). If you are still running a XenApp farm under version 6.0, this is the client you want to use.

Here’s the complete changelog:


HDX MediaStream

  1. With Adobe Flash Player ActiveX 11.4 installed on the client or endpoint device, Flash content cannot be redirected to be rendered on the client; instead, the content is rendered on the server.[From OnlinePlug-in_12.3.300][#LA2814]

HDX RealTime

  1. When using HDX RealTime Webcam Video Compression, the memory consumption of the wfica32.exe process might continue to increase while opening and closing the web camera on a Virtual Desktop Agent until the agent is restarted.[From OnlinePlug-in_12.3.300][#LA2254]


  1. Under certain conditions, changing the resolution of a virtual desktop session before the session disconnects unexpectedly, such as due to a network outage, can cause the session resolution to be different than expected after you reconnect.Note: Due to a functional limitation, this fix does not work for Virtual Desktop Agents running on Windows XP.[From OnlinePlug-in_12.3.300][#LA1377]
  2. Clicking an application icon multiple times in rapid succession can result in the creation of multiple, separate sessions even if the application limit is set to 1. To enable this fix, you must set the following registry key:HKEY_LOCAL_MACHINESOFTWARECitrixICA Client
    Name: EnableSyncLaunch
    Type: REG_DWORD
    Data: 1[From OnlinePlug-in_12.3.300][#LA2289]
  3. Attempts to shut down, restart, or log off a Windows XP endpoint might fail while connected to a virtual desktop session running in window mode until the virtual desktop session is closed.[From OnlinePlug-in_12.3.300][#LA1525]
  4. Microsoft Office Communicator, and other applications installed on a published desktop, automatically launches a client security dialog asking permission to use a microphone or a Webcam, even if neither is present in the session.[From OnlinePlug-in_12.3.300][#LA2575]
  5. When Auto Client Redirection is enabled, after choosing Hibernate, reconnection attempts might fail when the client is automatically closed.With this fix, the system can be suspended or sent into Hibernation mode with the USB device redirection, and can be auto-reconnected after the system returns from Standby mode.[From OnlinePlug-in_12.3.300][#LA3061]

System Exceptions

  1. Version 12.3 of the online plug-in might exit unexpectedly while disconnecting a session from a Web Interface site with a Microsoft Excel 2007 spreadsheet open.[From OnlinePlug-in_12.3.300][#LA2274]


  1. Input devices that fail to send certain scan codes might display incorrect characters (for example, for the the Ctrl+A, Ctrl+C, and Ctrl+V combinations) in client sessions. Affected devices include barcode scanners and Philips SpeechMike devices.To enable this fix, you must set the following registry key on the client device:HKEY_LOCAL_MACHINESOFTWARECitrixICA Client
    Name: AddScanCodes
    Type: REG_DWORD
    Data: 1[From OnlinePlug-in_12.3.300][#LA2516]
