Where to Find Documentation

This document describes the issue(s) resolved by this release and includes installation instructions. For additional product information, see Citrix eDocs, the Citrix Product Documentation Library.

Important Notes about This Release

• This cumulative update contains the latest fixes for Receiver for Windows 3.x. Because updates are cumulative, each new update contains all fixes, including security fixes, included in previous releases. Citrix recommends that you install this update only if you are affected by one or more of the issues resolved in this update. Citrix also recommends that you test this update before deploying it in a production environment.
• This release is based on Citrix Receiver for Windows 3.4. Any known issues in Version 3.4 of the product, except for the specific issues resolved in this release, still apply.
• Caution! This upgrade does not patch the existing installation - it fully replaces it with a new installation. As a result, uninstalling this package removes the entire component from the computer. If the need arises to revert to an earlier version of the product, you must uninstall this package and then reinstall the earlier version of the product. Reverting to an earlier version of the product might result in the loss of settings you configure while this upgrade is installed.
• Caution! This release may require you to edit the registry. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

Known Issues in This Release

• When using Internet Explorer and playing a YouTube video and then clicking a link on the same YouTube page to a different YouTube video, the new YouTube page opens as expected but the original video keeps playing in place of the new video. As a workaround, refresh the new YouTube page. [BUG0427892]
• When using Internet Explorer 10, videos on certain Web sites can fail to start rendering. The issue occurs when Internet Explorer 10 fails to detect the correct Document Mode. As a workaround, select a different Document Mode for Internet Explorer 10, or view the Web page in Compatibility Mode. [BUG0432934]
• When using Internet Explorer 11 and launching a connection through a Web Interface site, a pop-up appears to Open/Save the ICA file. As a workaround, add the Web Interface sites to Compatibility View Settings in Internet Explorer 11. [BUG0435129]

New Fixes in This Release

This cumulative update introduces the following new fixes:

Content Redirection

1. With legacy client drive mapping enabled as described in Knowledge Center article CTX127968, client to server content redirection does not work when launched within a XenDesktop session.

   [From RcvrforWin3.4_13.4.300][#LA4108]

HDX MediaStream

1. When playing several multimedia files in rapid succession on http://www.youtube.com/ with HDX MediaStream Flash Redirection enabled, the PseudoContainer2.exe process might exit unexpectedly.

   [From RcvrforWin3.4_13.4.300][#LA3846]

2. The HDX MediaStream Flash Redirection feature might fail if Adobe Flash Player 11.8.800.94 or later is installed on the client.

   [From RcvrforWin3.4_13.4.300][#LA5035]

3. Browsing certain Web sites with HDX MediaStream Flash Redirection enabled can cause Internet Explorer to become unresponsive.

   To enable this fix, you must also install VDA/HDX Mediastream for Flash Fix #LA4151 and set the following registry key on the VDA/XenApp server:

   HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\HdxMediaStreamForFlash\Server\PseudoServer
   Name: SupportedUrlHeads
   Type: REG_MULTI_SZ
   Data: <each value on a separate line, null separated:>
   http://
   https://
   file://

   [From RcvrforWin3.4_13.4.300][#LA5255]

4. With HDX Mediastream for Flash Version 1.0 (First Generation Flash Redirection) enabled, Microsoft Internet Explorer might exit unexpectedly while Adobe Flash Player 11.8 or later is installed.

   [From RcvrforWin3.4_13.4.300][#LA5421]

HDX MediaStream Windows Media Redirection

1. Pressing Replay or dragging Windows Media Player off the screen and back causes a black rectangle to appear and obscure the top left corner of the video playback.

   [From RcvrforWin3.4_13.4.300][#LA3999]

2. In Version 3.4 of Receiver for Windows with HDX MediaStream Windows Media Redirection enabled, a delay of up to ten seconds can be observed before a multimedia file starts to stream.

   [From RcvrforWin3.4_13.4.300][#LA4141]

HDX Plug and Play

1. While in a session, the Receiver for Windows might become unresponsive when removing a USB device from the endpoint.

   [From RcvrforWin3.4_13.4.300][#LA4827]

Installing, Uninstalling, Upgrading

1. After upgrading to Receiver 3.x, users cannot launch published applications and the following error message appears:

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

   [From RcvrforWin3.4_13.4.300][#LA3120]

2. Attempts by non-administrative users to upgrade the Receiver for Windows might result in the partial installation of the receiver if the receiver was installed by an administrator.

   With this fix, a non-administrative user attempting to upgrade a receiver installed by an administrator receives an error message and the installation process is terminated.

   [From RcvrforWin3.4_13.4.300][#LA3425]

Keyboard

1. This fix addresses an issue that can cause the state of the Caps Lock, Num Lock, and/or Scroll Lock keys to be out of sync in an ICA session. This fix introduces a new parameter that allows you to force the synchronization of the keyboard LED state between the client and the server. To enable this option, add the entry "KeyboardForceLEDUpdate = On" to the [WFClient] section of the appsrv.ini file in the local user profile location or of the default.ica file in the corresponding Web Interface site.

   [From RcvrforWin3.4_13.4.300][#LA3682]

2. This fix addresses an LED synchronization issue that can cause the state of the Caps Lock, Num Lock, and/or Scroll Lock keys to be out of sync between the client and server.

   [From RcvrforWin3.4_13.4.300][#LA4293]

Local App Access

1. With Local App Access enabled, clicking the Desktop Viewer causes the client local taskbar to appear needlessly.

   [From RcvrforWin3.4_13.4.300][#LA3049]

2. Setting HKEY_CURRENT_USER\SOFTWARE\Citrix\PNAgent\FavorLocalApps = 1 (REG_DWORD) to make local applications the default programs for specified file types does not work. Instead, the equivalent published applications are invoked by default.

   Note: After installing this fix, delete HKEY_CURRENT_USER\SOFTWARE\Citrix\PNAgent\FavorLocalLast if it is the same as HKEY_CURRENT_USER\SOFTWARE\Citrix\PNAgent\FavorLocalApps.

   [From RcvrforWin3.4_13.4.300][#LA3776]

3. With Local App Access enabled, the local endpoint device taskbar might overlap the VDA taskbar if the mouse is positioned at the edge of the screen.

   [From RcvrforWin3.4_13.4.300][#LA4188]

Logon/Authentication

1. The registry setting described in Knowledge Center article CTX127887 to set the Receiver logon screen timeout to never expire does not work with Version 3.x. of Receiver for Windows. After installing this fix, setting the registry key as described in the article successfully keeps the logon screen from being minimized.

   [From RcvrforWin3.4_13.4.300][#LA4253]

2. Pass-through authentication fails if the ssonsvr.exe process fails to launch before pnamain.exe starts up. This fix allows you to configure the time interval that pnamain.exe waits for ssonsvr.exe to launch.

   To enable this fix, must set the following registry key:

   HKEY_LOCAL_MACHINE\Software\Citrix\PNAgent OR HKEY_CURRENT_USER\Software\Citrix\PNAgent
   Name: SSONWaitCounter
   Type: REG_DWORD
   Data: <time in 100 milliseconds; if the value is less than 10, 10 is applied by default>

   Note: If you set HKEY_LOCAL_MACHINE\Software\Citrix\PNAgent, changes to HKEY_CURRENT_USER\Software\Citrix\PNAgent have no effect. If you do not set HKEY_LOCAL_MACHINE\Software\Citrix\PNAgent, changes to HKEY_CURRENT_USER\Software\Citrix\PNAgent take effect effect.

   [From RcvrforWin3.4_13.4.300][#LA4154]

3. This issue affects only Receiver for Windows 3.x Enterprise: When switching from pass-through mode to prompt mode, the Domain name field of the logon screen fails to be populated.

   [From RcvrforWin3.4_13.4.300][#LA4228]

4. Pass-through authentication might fail to work after installing XenDesktop 7 VDA on Windows Server 2008 R2. The issue occurs because the ssonsvr.exe process fails to start.

   [From RcvrforWin3.4_13.4.300][#LA4685]

Printing

1. When sending multiple Adobe Acrobat print jobs to a session printer, random pages or entire print jobs can be lost.

   [From RcvrforWin3.4_13.4.300][#LA3643]

2. Session printer enumeration can take an excessive amount of time.

   [From RcvrforWin3.4_13.4.300][#LA3951]

3. When configuring Local Printer Settings in Internet Explorer 8 to print multiple pages per sheet, the setting might not be honored; instead one page per sheet is printed. The issue occurs in scenarios where you connect from a XenApp 6.5 published desktop to an instance of Internet Explorer 8 published on a XenApp 6 server.

   [From RcvrforWin3.4_13.4.300][#LA3379]

4. Attempts to print an HTML document using Internet Explorer 9 can result in garbled output in the Citrix Print Viewer (cpviewer.exe) and the printout for certain type of fonts.

   [From RcvrforWin3.4_13.4.300][#LA3962]

5. The print preview might fail to open in the XPS Viewer on Windows 8 client devices.

   [From RcvrforWin3.4_13.4.300][#LA5229]

Session/Connection

1. The Desktop Viewer (CDViewer.exe) and wfica32.exe processes might exit unexpectedly while reconnecting to a virtual desktop session.

   [From RcvrforWin3.4_13.4.300][#LA3944]

2. Receiver with Desktop Lock presents a gray screen each time there is a hardware failure or if the VM is forcefully shut down from the hypervisor.

   [From RcvrforWin3.4_13.4.300][#LA3499]

3. The Receiver can become unresponsive when you click the Devices button of the Desktop Viewer toolbar while the "Citrix Receiver – Device Access" dialog box is displayed. This dialog box appears if the device access preference is configured to "Ask me each time" instead of the default "Do nothing."

   [From RcvrforWin3.4_13.4.300][#LA3899]

4. After launching and exiting the Self-service Plug-in, Event ID 0 might be displayed under SelfServicePlugin.exe in the Event log.

   [From RcvrforWin3.4_13.4.300][#LA3926]

5. With this fix, the IsReconnectInProgress() API is integrated to Citrix Fast Connect 2.0. The feature determines whether the reconnect process is in progress or not while the Auto Client Reconnect feature is enabled.

   [From RcvrforWin3.4_13.4.300][#LA4080]

6. This fix allows pass-through applications to be reconnected and enables Workspace Control for pass-through applications.

   To enable the fix, you must set the following registry keys:

   To enable Workspace Control in pass-through mode:

   HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\PNAgent
   Name: ForceEnableWSC
   Type: DWORD
   Data = 1

   To enable pass-through applications to be reconnected:

   HKEY_LOCAL_MACHINE\Software\Citrix\ICA Client
   Name: BypassPassThruMode
   Type: DWORD
   Data = 1

   Note: This fix works only under the following conditions:

   • The two or more connection hops cannot occur within the same XenApp Services site or farm. In other words, the endpoint Receiver can connect to a XenDesktop VDA published on XenApp Services Site A, and then the pass-through client on that VDA can connect to a published application or desktop on a different XenApp Services site, Site B.
   • The second connection hop must be to a XenApp terminal session; it cannot be to a XenDesktop VDA.

   [From RcvrforWin3.4_13.4.300][#LA4206]

7. The pass-through client on a VDA accesses the rasphone.pbk file every 3 seconds, which can impact the network storage performance.

   [From RcvrforWin3.4_13.4.300][#LA4278]

8. When launching a published application in seamless mode, the progress bar window remains in the background.

   To enable the fix, set the following registry keys on the client-side:

   • For Windows 32-bit systems:
     HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client
     Name: ForegroundProgressBar
     Type: DWORD
     Data: 00000001
   • For Windows 64-bit systems:
     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client
     Name: ForegroundProgressBar
     Type: DWORD
     Data: 00000001

   [From RcvrforWin3.4_13.4.300][#LA3491]

9. When a client device is in the sleep or hibernation state for an extended period of time with an active XenDesktop session running, upon resuming, the session might fail to reconnect as expected and become stuck in a reconnection phase requiring the session window to be manually closed.

   This fix addresses the issue so that upon resuming the client device, the session window closes as expected when reconnection fails.

   [From RcvrforWin3.4_13.4.300][#LA2748]

10. When using remote assistance software in a desktop that is published to be an odd (non-even) percentage of the client screen (for example, 95%), the remote assistance session might appear to be distorted.

    [From RcvrforWin3.4_13.4.300][#LA4313]

11. This compatibility enhancement extends support for HDX Plug and Play USB device redirection to additional USB devices.

    [From RcvrforWin3.4_13.4.300][#LA4335]

    [From RcvrforWin3.4_13.4.300][#LA4344]

14. With the "Hide Icon" policy enabled, the "About Citrix Receiver" window might appear automatically after logging on to the client device.

    [From RcvrforWin3.4_13.4.300][#LA4513]

15. With Multi-Stream enabled, Receiver with Desktop Lock might fail to recover from a VDA screen saver and fail to reconnect after a VDA is locked.

    [From RcvrforWin3.4_13.4.300][#LA4097]

16. After resuming an endpoint from Sleep or Hibernate mode while connected to a XenApp or a XenDesktop session using Receiver for Windows, copy/paste operations between that endpoint and Citrix session can fail.

    [From RcvrforWin3.4_13.4.300][#LA3973]

17. Connecting from within one XenDesktop session to another can result in the consumption of two device licenses.

    [From RcvrforWin3.4_13.4.300][#LA3985]

18. On VOIP calls made from a PVS streamed VDA using HollyCRM with the Huawei OpenEye plugin, neither side might hear the other after two hours or more.

    [From RcvrforWin3.4_13.4.300][#LA4809]

19. Logons and logoffs to and from a Windows 7 client device with Receiver for Windows Enterprise Edition installed can be delayed. The issue occurs when logon/logoff scripts are applied by a GPO. Each script can cause a significant delay.

    [From RcvrforWin3.4_13.4.300][#LA3811]

20. If an endpoint with Desktop Lock is logged on without a network connection, the connection screen "Please Wait: Preparing your desktop..." remains displayed indefinitely. Even after the network connection is recovered, the connection screen remains displayed.

    With this enhancement, the following message appears after a few seconds and the endpoint is automatically logged off:

    "Citrix Receiver could not contact the server. Please check your network connection."

    [From RcvrforWin3.4_13.4.300][#LA2338]

21. Attempts to launch a session using a custom virtual driver can fail.

    To enable the fix, you must create the following registry key:

    • On 32 bit Windows
      HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client
      Name: VdLoadUnLoadTimeOut
      Type: REG_DWORD
      Data: Any value in seconds
    • On 64 bit Windows
      HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432node\Citrix\ICA Client
      Name: VdLoadUnLoadTimeOut
      Type: REG_DWORD
      Data: Any value in seconds

    [From RcvrforWin3.4_13.4.300][#LA4540]

22. When using Citrix Receiver within a virtual desktop session, attempts to launch XenApp published applications fail and the following error message appears:

    "This version of Citrix Receiver does not support selected encryption. Please contact your administrator. [Error 1029: Invalid DLL load]."

    [From RcvrforWin3.4_13.4.300][#LA4743]

    [From RcvrforWin3.4_13.4.300][#LA3781]

26. When pressing the Windows key or clicking the Start button to open the client-side Start menu with a seamless session window running in the foreground, clicking the taskbar icon of a local window causes the focus to remain on the seamless session window instead of shifting to the local window.

    [From RcvrforWin3.4_13.4.300][#LA5089]

27. The ICA file might not be automatically removed when logging off from a desktop session while using Receiver for Windows.

    [From RcvrforWin3.4_13.4.300][#LA5536]

Shadowing

1. Attempts by administrators to shadow a session can result in a black shadowing session to be initiated that might fail to redraw automatically. The issue occurs if the shadower and shadowee windows are of the same size.

   [From RcvrforWin3.4_13.4.300][#LA2913]
