    • On Windows 64-bit systems:
      HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client
      Name: ProcessWM_SETTINGCHANGE
      Type: DWORD
      Value: 1 (default value is zero) (this fix is only for users who disable CDViewer Bar and run Desktop in full-screen mode)

    The following registry keys are optional. By default, this value is 0 and is needed only when the default configuration does not solve the issue.

    [From RcvrForWin4.2_14.2.100][#LC0780]

  6. When importing the Client Selective Trust registry key file as described in Knowledge Center article CTX133565 and configuring both the trusted and intranet zones, if the Desktop Viewer is enabled in the Web Interface or in StoreFront, the registry key might not work. If the Web Interface or StoreFront URL is configured as a trusted zone in the browser, a file security prompt incorrectly appears when accessing the Client Drive Mapping (CDM) directory.

    [From RcvrForWin4.2_14.2.100][#LC0904]

  7. After logging off from a desktop session, if the user attempts to log off from the Windows XP Embedded Thin Client, the error message "End program concentr.exe" appears.

    [From RcvrForWin4.2_14.2.100][#LC2556]

  8. The time zone is not correct when users log on with Receiver for Windows. For this hotfix to work, the following must occur:

    • The same Microsoft time zone update hotfix must be installed on the user device and the server. For example, if Microsoft hotfix KB2998527 is installed on the user device, install this hotfix on the server.
    • If the server operating system is Windows Server 2008 R2 Service Pack 1, Microsoft hotfix KB2870165 must be installed on the server.
    • Fix #LC1061 must be installed on the XenApp server.

    [From RcvrForWin4.2_14.2.100][#LC1392]

  9. This fix enables FastConnect Scripting API support without integrating with the Self-Service Plug-in. This can be enabled by using the group policy under ADM > Citrix Components > Citrix Receiver > FastConnect API Support > Manage FastConnectAPI support and then by clearing the option "Integrate Self Service plugin with FastConnect." You can also change the registry key "FastConnectUsingSSP" to "False" under HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Citrix\Dazzle.

    [From RcvrForWin4.2_14.2.100][#LC2580]

  10. When "SelfServiceMode" is set to "False", Start Menu shortcuts are created for background sessions, such as the Pre-launch application.

    [From RcvrForWin4.2_14.2.100][#LC1760]

  11. This fix addresses the following issues:

    • When starting a seamless published application, the application might open behind the Windows taskbar.
    • When moving the Windows taskbar to another location, the seamless session fails to resize and the taskbar might overlap with the seamless application.

    To enable this fix, you must also install the server-side Fix #LC1342.

    [From RcvrForWin4.2_14.2.100][#LC1645]

  12. An error message might appear when starting a session in Receiver for Windows 4.2 on Windows XP Embedded thin client.

    [From RcvrForWin4.2_14.2.100][#LC1929]

  13. This fix enables FastConnect Scripting API support while installing by setting "FastConnectAPISupportEnabled=True." You can also enable this setting through the Group Policy object "Enable FastConnect API Functionality" under "Manage FastConnectAPI support."

    [From RcvrForWin4.2_14.2.100][#LC2131]

  14. The Receiver for Windows 4.2 might stop sending network packets because of a program deadlock. As a result, the following can occur:

    • The session might not be established.

    [From RcvrForWin4.2_14.2.100][#LC2573]

  20. After installing the Receiver by using the command line, a new store is automatically added in the Self-Service Plug-in when stopping and restarting the Receiver.

    The issue occurs when the "Dazzle" key under HKEY_CURRENT_USER\Software\Citrix has a subkey called as "Properties" and the "RegDeleteKey" cannot delete the registry key that contains the subkeys and this creates duplicate store keys.

    [From RcvrForWin4.2_14.2.100][#LC2154]

  21. Application shortcuts are left behind in the desktop shortcut folder or on the Start menu when users log off by using Fast Connect Scripting APIs.

  25. This feature enhancement includes the "Per App shortcut management" option. By using Application properties, you can create shortcuts on the user's desktop and on the Start menu for specific published applications.

    Note: The Start menu folder of the Application properties is honored only if users connect to the farm or delivery group by using the Web Interface instead of StoreFront.

    [From RcvrForWin4.2_14.2.100][#LC1930]

  26. When users log off from the Receiver by using Fast Connect, the subscription list of applications continue to appear in the side pane.

    [From RcvrForWin4.2_14.2.100][#LC2574]

  27. If Receiver for Windows is not configured with an account, applications cannot disconnect by using the disconnect SelfService command.

    [From RcvrForWin4.2_14.2.100][#LC2128]

System Exceptions

  1. The Receiver might experience an access violation and close unexpectedly. When this occurs, users cannot start sessions by clicking application icons in the Web Interface.

    [From RcvrForWin4.2_14.2.100][#LC0650]

  2. When starting a published application with a local printer attached to the user device, Receiver for Windows might close unexpectedly with the following error message:

    "Citrix HDX Engine has stopped working"

    [From RcvrForWin4.2_14.2.100][#LC1170]

User Experience

  1. With this fix, the Group Policy Object settings are given higher precedence than the primary store when reading the configuration for a session.

    [From RcvrForWin4.2_14.2.100][#LC2698]

User Interface

  1. After installing the Receiver by using the command line, the store name and the description is set as existing. If the Receiver is restarted, the store name and the description might change automatically to another value. However, the URL remains the same and the connection works correctly.

    The issue occurs because when processing the Receiver sites, the store name is not retrieved from the registry; instead a new store name is generated according to the store URL.

    [From RcvrForWin4.2_14.2.100][#LC1231]

  2. This enhancement suppresses the prompt to remove applications from the application list and shortcuts if the application is no longer published or is disabled.

    [From RcvrForWin4.2_14.2.100][#LC2157]

    [#LC0150]

  2. Occasionally, accessing a web site that contains a "HEAD" request in the URL header instead of a "GET" request might fail if the web server fails to accept the HEAD request. As a result, server-to-client content redirection does not work.

    To enable the fix, create the following registry key:

    HKEY_CURRENT_USER_\Software\Citrix\ICA Client\Engine
    Name: SpecificSites
    Type: REG_MULTI_SZ
    Value: web site names (one web site per line)

    Note: A GET request rather than HEAD request is sent to any web site specified in the value. The web site name is case sensitive and wildcard '*' is supported. For example, if "*.mycompany.com" is specified in this registry value, users can access both www.mycompany.com and support.mycompany.com which are the "specific" web sites.

    [#LC0326]

  3. This fix is an enhancement to Fix #LA0803. On servers with XenApp 6 Hotfix Rollup Pack 2 and XenApp 6.5 Hotfix Rollup Pack 3 installed, when accessing custom URLs within a published application, server-to-client content redirection does not work and a web browser opens on the server instead of the user device.

  5. If the user device does not have a connected webcam, attempts to start a published instance of Microsoft Lync 2010 might result in the application connecting and disconnecting several times before establishing a final connection and starting the application. This can occur if you install an application that installs a webcam when no other webcams are installed, such as the Motorola Bluetooth package.

    [From RcvrForWin4.1_14.1.100][#LA4867]

  6. When starting a published application or a desktop, Kerberos authentication might not work when using pass-through authentication on an IPv4 network. This release fixes the issue for IPv4 networks only.

    [From RcvrForWin4.1_14.1.100][#LA5026]

  7. This fix addresses audio/video issues related to the Microsoft Lync 2013 VDI Plug-in for Windows. It improves the user experience for Lync users. For more information, see Knowledge Center article CTX138408.

    [From RcvrForWin4.1_14.1.100][#LA5314]

  8. If the CANcaseXL USB network adapter is redirected into a virtual desktop, it appears to malfunction in Windows Device Manager. This USB device does not support the Citrix USB redirection driver. The VDA requires installation of Fix #LA5022 in order to work properly.

    [From RcvrForWin4.1_14.1.100][#LA5022]

  9. This fix reworks Fix #LA1257, which fails to fully address the following issue:

    With the Desktop Viewer disabled, a full-screen client session does not adjust the screen resolution of the Virtual Desktop Agent in response to a change in screen resolution on the endpoint.

    [From RcvrForWin4.1_14.1.100][#LA4000]

  10. When connectivity to a XenDesktop session is lost for an amount of time that exceeds the Session Reliability timeout, DesktopViewer remains onscreen indefinitely. The session itself disappears, as expected, from the Connection Center after the Session Reliability timeout.

    [From RcvrForWin4.1_14.1.100][#LA4856]

System Exceptions

  1. The wfica32.exe process can exit unexpectedly and the following error message appears:

  1. When connecting or reconnecting to a session hosted on XenApp for Unix, no screen updates occur for 90 seconds.

    [From RcvrForWin4.1_14.1.100][#LA5244]

User Interface

  1. A change introduced in Version 12.1 of the online plug-in introduced a delay in the appearance of the connection progress bar for seamless connections. However, for sessions connecting to slower servers, this behavior is not always desirable. This enhancement introduces support for the following registry key that allows you to configure the duration of the delay:

    On 32-bit Windows:

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client
    Name: NotificationDelay
    Type: REG_DWORD
    Data: <Delay, in milliseconds>

    On 64-bit Windows:

    [#LA3348]

Installing, Uninstalling, Upgrading

  1. 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.

    [#LA3425]

Keyboard

  1. When using version 3.3. of the Receiver for Windows, pressing the Alt key can cause the key to remain in a down state. As a result, pressing the "E" key subsequently can invoke Windows Explorer.

    [#LA3288]

  2. When clicking the Desktop Viewer toolbar with the Windows key pressed in full-screen mode, the key might remain in a down state. As a result, pressing the "E" key subsequently invokes Windows Explorer.

    [#LA3349]

  3. 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.

    [#LA3682]

  4. 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.

    [#LA4293]

Local App Access

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

    [#LA3049]

Logon/Authentication

    [#LA4685]

Printing

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

    [#LA3643]

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

    3. [#LA3951]

Session/Connection

  1. 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.

    [#LA2748]

  2. 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: 1
    • For Windows 64-bit systems:
      HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client
      Name: ForegroundProgressBar
      Type: DWORD
      Data: 1

    [#LA3491]

  3. 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.

    [#LA3499]

  4. With Taskbar Grouping enabled on the client device, TaskbarGrpXpVista.dll - within wfica32.exe - unnecessarily queries the client device for information about published applications running in the session. For example, when running a published instance of cmd.exe, TaskbarGrpXpVista.dll queries C:\windows\system32\cmd.exe for information about the executable. In scenarios where the published application is running from the remote share, this can cause undesirable bandwidth consumption.

    [#LA3661]

  5. With a GPO setting in place to prevent taskbar grouping, clicking taskbar icons on Windows XP and Vista client devices fails to switch focus to the associated windows.

    [#LA3889]

  6. The Receiver can become unresponsive when you click the Devices button of the Desktop Viewer toolbar while the "Citrix Receiver â?? 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."

    [#LA3899]

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

    [#LA3944]

  8. 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.

    [#LA4080]

  9. 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.

    [#LA4206]

  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.

    [#LA4313]

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

    [#LA4335]

  12. A deadlock in wfcrun32.exe can prevent new sessions from launching successfully.

    [#LA4344]

  13. Attempts to connect to XenApp servers using the Citrix Quick Launch tool or static ICA files that specify "HTTPBrowserAddress=ServerName_Or_IP:Port" (for example: "HTTPBrowserAddress=192.168.1.10:8080") can fail.

    [#LA4585]

System Exceptions

  1. The wfica32.exe process can exit unexpectedly and the following error message appears:

    "Citrix HDX Engine has encountered a problem and needs to close."

    [#LA3412]

  2. The wfica32.exe process might experience an access violation and exit unexpectedly.

    [#LA3639]

  3. The wfica32.exe process might exit unexpectedly.

    [#LA4208]

User Experience

  1. This fix eliminates the unnecessary appearance of logon prompts when Receiver 4.0 is used with StoreFront.

    [#LA4652]

HDX MediaStream Flash Redirection

  1. Moving a video window offscreen in whole or in part while a video file is rendering can leave a dark area on the screen. The dark area remains even after moving the video window back.

    [#LA0599]

  2. Important: Before applying this fix on a client device, see Knowledge Center article CTX126817 for important information about how the Dynamic Blacklist feature might affect client-side Flash redirection.

    In scenarios where the Enable server-side content fetching policy is enabled on the server and the Flash server-side content fetching URL list setting is configured for the Flash Redirection policy on the client, attempts to play Flash content fail if the URL to the content contains multibyte/unicode characters such as those common in Asian languages

    To enable this fix in its entirety, you must install both a client hotfix that contains Fix #LA1621 and:

    • For XenApp: an HDX Flash hotfix that contains Fix #LA1621
    • For XenDesktop: a Virtual Desktop Agent hotfix that contains Fix #LA1621

    Note: This fix also requires the corresponding language code pages to be installed on both the client and the server. The code pages are installed by default by the Windows operating system. For example, the Japanese distribution of Windows 7 installs the Japanese code pages by default. However, if you are using a URL with Japanese characters on an English distribution of Windows 7, the Japanese code pages must be installed explicitly. This applies to both the client and the server because the URLs are transferred from the client to the server when server-side content fetching is enabled.

    [#LA1621]

  3. Certain user interactions with Flash content, such as clicking buttons, can cause Pseudocontainer2.exe to exit unexpectedly.

    [#LA1948]

  4. Client-side content redirection can fail for certain types of Flash content and revert to server-side rendering, including cases where:

    1. Flash content tries to download another Flash file that does not exist or cannot be located
    2. Flash content created by Adobe Captive fails some logic checks of the client-side content redirection feature
    3. Flash content causes the client-side content redirection feature to remote unsupported interfaces to the server
    4. The client attempts to fetch Flash content even if its URL is configured in the ServerContentFetching URL blacklist

    To enable this fix, you must install both an HDX Flash and a Receiver for Windows hotfix that contains Fix #LA2198. To enable this fix for issue #1 above, you must also set the following registry key on the client:

    • On 32-bit Windows:
      HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\HdxMediaStreamForFlash\Client\PseudoContainer
      Name: FallbackIfFlashNotExist
      Type: REG_DWORD 
      Data: 0
    • On 64-bit Windows:
      HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\HdxMediaStreamForFlash\Client\PseudoContainer
      Name: FallbackIfFlashNotExist
      Type: REG_DWORD 
      Data: 0

    [#LA2198]

  5. When switching the focus from the Flash window (- a child window of a Web browser running seamless window) to a local window and switching the focus back to the address bar of the seamless browser window, attempts to type in the browserâ??s address bar can fail.

    [#LA2685]

  6. Important: Before applying this fix on a client device, see Knowledge Center article CTX126817 for important information about how the Dynamic Blacklist feature might affect client-side Flash redirection.

    The HDX MediaStream Flash Redirection feature might fail to work on Dailymotion videos (http://www.dailymotion.com) with an error. The issue occurs when the client and server are located in different geographical locations.

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

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\HdxMediaStreamForFlash\Client
    Name: DisableRegionFiltering
    Type: REG_DWORD
    Data: 1

    [#LA3134]

HDX Plug and Play

  1. This feature enhancement modifies the default USB Redirection behavior as follows:

    • When the Desktop Viewer is enabled, users can manually redirect USB devices.
    • When the Desktop Viewer is not enabled, USB devices are automatically redirected.

    [#LA0108]

  2. After failed attempts to map certain USB devices into a virtual desktop session, the devices disappear from the Device Manager until you restart the endpoint.

    [#LA0954]

  3. Clicking Devices within the Desktop Viewer to select a USB device to be remoted using HDX Plug-n-Play USB Device Redirection can cause the Desktop Viewer to become unresponsive.

    [#LA3348]

Installing, Uninstalling, Upgrading

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