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.
• Citrix Receiver for Windows 3.4 (13.4.400) can be upgraded to Citrix Receiver for Windows 4.2 only. To upgrade from 3.4 (13.4.400) to other 4.x versions, 13.4.400 must be uninstalled first.

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. When accessing the URLs within a published application, the server-to-client content redirection might not work and can open a browser on the server and fails to open on the client.

   [From RcvrforWin3.4_13.4.400][#LC0150]

2. This is an enhancement, previously available in Version 12.x of the online plug-in, that allows you to enable custom protocols for server to client content redirection.

   The following protocols are supported and enabled by default:

   • HTTP (Hypertext Transfer Protocol)
   • HTTPS (Secure Hypertext Transfer Protocol)
   • RTSP (Real Player and QuickTime)
   • RTSPU (Real Player and QuickTime)
   • PNM (Legacy Real Player)
   • MMS (Microsoft Media Format)

   To add support for additional protocols:

   1. Deploy this version of Receiver.
   2. Import the ICA Client policy settings using one of the methods described in eDocs at http://support.citrix.com/proddocs/topic/receiver-windows-enterprise-3x/ica-import-icaclient-template-v2.html.
   3. Under Computer Configuration > Administrative Templates > Classic Administrative Templates (ADM) > Citrix Components > Citrix Receiver , edit the SFTA Extra URL protocols setting for the protocols for which you want to enable redirection. Use the following format and separate protocols by a semicolon (;):
      protocol1://;protocol2://

   [From RcvrforWin3.4_13.4.400][#LA0803]

3. 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.

   [From RcvrforWin3.4_13.4.400][#LC0326]

4. 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.

   [From RcvrforWin3.4_13.4.400][#LC0428]

HDX MediaStream

1. When playing a video in Windows Media Player within a Receiver session, a second black window opens with the title "Citrix HDX Movie Window." Closing this secondary window does not have an effect on the video that is playing.

   [From RcvrforWin3.4_13.4.400][#LC0818]

Logon/Authentication

1. Domain pass-through authentication can fail intermittently for Citrix Receiver for Windows 3.4 with Cumulative Update 3.

   [From RcvrforWin3.4_13.4.400][#LC0865]

2. When a user logs on by using the Universal Principal Name (UPN) format and the account is disconnected from the domain, the single sign-on process (SSONSvr.exe) prompts users for a password instead of providing the credentials automatically in Receiver for Windows.

   To enable the fix, create the following registry key:

   • On 32-bit Windows:
     HKEY_LOCAL_MACHINE\Software\Citrix\ICA Client\SSON
     Name: UPNConversion
     Type: REG_SZ
     Value: True
   • On 64-bit Windows:
     HKEY_LOCAL_MACHINE\Software\Wow6432Node\Citrix\ICA Client\SSON
     Name: UPNConversion
     Type: REG_SZ
     Value: True

   [From RcvrforWin3.4_13.4.400][#LA5334]

Printing

1. Automatic creation of printers is limited to 100 per session.

   [From RcvrforWin3.4_13.4.400][#LC0031]

Server/Farm Administration

1. This fix disables the SSLv3 protocol due to the POODLE security issue described in CVE-2014-3566. This version of the Receiver supports TLS 1.0 only. For more information, see Knowledge Center article CTX200238.

   [From RcvrforWin3.4_13.4.400][#LC1401]

Session/Connection

1. Session sharing might fail if the XenApp base installation was performed in a non-default location, such as on the server's D: drive.

   To enable the fix, create the following registry key:

   HKEY_LOCAL_MACHINE\Software\Wow6432Node\Citrix\ICA Client\Passthru
   Name: IMAInstallationPath
   Type: REG_SZ
   Value: Customized IMA installation path (default installation path is C:\Program Files (x86)\Citrix\system32\Citrix\IMA)

   [From RcvrforWin3.4_13.4.400][#LA5780]

2. When attempting to transfer a file by using a twain device with any third-party application, the application might exit unexpectedly.

   [From RcvrforWin3.4_13.4.400][#LC0369]

3. Typing in published instances of Microsoft Outlook can cause the session to disconnect at random.

   [From RcvrforWin3.4_13.4.400][#LC0323]

4. COM port redirection can fail with the following error message:

   "Error in OpenPort: Comport 'COM4'"

   [From RcvrforWin3.4_13.4.400][#LC0434]

5. When attempting to open a Microsoft Word or Microsoft Excel 2003 file from a client drive mapped into the session with read-only access, the file might fail to open.

   [From RcvrforWin3.4_13.4.400][#LA4198]

6. In pass-through client sessions, if multiple published application shortcuts are present in the Startup folder of a published desktop, the top-most published application in the startup folder might launch multiple times while other applications in the Startup folder fail to launch.

   Note: The issue occurs only in scenarios where the published desktop and the applications are hosted on the same XenApp server.

   [From RcvrforWin3.4_13.4.400][#LA5118]

7. When XenApp is configured for either Direct or NTLM authentication, proxy connections to external web sites might fail from Citrix Receiver for Windows Version 3.x.

   [From RcvrforWin3.4_13.4.400][#LA4847]

8. 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 RcvrforWin3.4_13.4.400][#LA4000]

9. 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 RcvrforWin3.4_13.4.400][#LA4856]

10. If users save their passwords in Citrix Receiver by selecting the "Save Password" check box and the network connection is temporarily disabled and then enabled again, attempts to start an application by using the "pnagent.exe/Qlaunch" command can fail and the logon dialog box appears. The issue also occurs while stopping or restarting Internet Information Services (IIS) on the Web Interface server.

    [From RcvrforWin3.4_13.4.400][#LC0183]

11. If NativeDriveMapping is set to "TRUE" or "FALSE" and UNCEnabled is set to "0" in a XenApp pass-through session, File Type Association (FTA) might fail for Citrix Receiver Enterprise Edition. For example, when accessing a published desktop on Server 1 from a user device, the drives are mapped in the session. On the published desktop, Receiver is configured to open all .doc files with a published version of Word that is hosted on Server 2. When you double-click on a .doc file on a mapped drive in the published desktop, an error message appears.

    [From RcvrforWin3.4_13.4.400][#LC1147]

12. Citrix Receiver for Windows 13.4 Cumulative Update 3 might exit unexpectedly for published SAP applications with the following error message:

    "Citrix HDX Engine has stopped working"

    [From RcvrforWin3.4_13.4.400][#LC0712]

13. When users connect to a Windows 7 VDA by using Receiver for Windows, if the user redirects the SpeechMike by using Desktop Viewer, the redirection might fail when the microphone button is released.

    [From RcvrforWin3.4_13.4.400][#LC0510]

14. During session pre-launch in non-English XenApp environments, the Citrix Receiver progress bar might become visible and unresponsive with the following error message:

    "Connection Established, Negotiating Capabilities"

    [From RcvrforWin3.4_13.4.400][#LC0306]

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."

   [From RcvrforWin3.4_13.4.400][#LA3412]

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

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

   [From RcvrforWin3.4_13.4.400][#LA3964]

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

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

   [From RcvrforWin3.4_13.4.400][#LA4695]

4. If the Multi-Stream policy is enabled, applications can become unresponsive when accessing the COM port.

   [From RcvrforWin3.4_13.4.400][#LA5543]

User Experience

1. If users open multiple Excel workbooks and Excelhook is enabled in the registry, when closing the last workbook the Excel taskbar icon disappears, even though the Excel window is open.

   [From RcvrforWin3.4_13.4.400][#LC0062]

2. When users start a session without using Desktop Viewer in full screen mode or by using a Desktop Lock on a user device in a multi-monitor environment, scroll bars might appear in the Receiver session window when unplugging an external monitor. Additionally, the session resolution can also change.

   To enable the fix, create the following registry key:

   • On 32-bit Windows:
     HKEY_LOCAL_MACHINE\Software\Citrix\ICA Client
     Name: ResolutionUpdateDelay
     Type: REG_DWORD
     Data: 1000, 1500, 2000 and so on (time in milliseconds, 2000 is the recommended value)
   • On 64-bit Windows:
     HKEY_LOCAL_MACHINE\Software\Wow6432Node\Citrix\ICA Client
     Name: ResolutionUpdateDelay
     Type: REG_DWORD
     Data: 1000, 1500, 2000 and so on (time in milliseconds, 2000 is the recommended value)

   [From RcvrforWin3.4_13.4.400][#LA5468]

3. If folder redirection is enabled on a Windows-based computer, when users log on with Program Neighborhood Agent, the folder with published application shortcuts is created slowly and there is a delay between the appearance of each icon.

   [From RcvrforWin3.4_13.4.400][#LA5923]

User Interface

1. After changing the desktop color scheme from the default color blue to other colors, such as Olive Green or Silver (Desktop > Properties > Appearance tab > Color scheme), the text and the background color of Self-service Plug-in become identical, making it impossible to read menu items.

   [From RcvrforWin3.4_13.4.400][#LA5121]
