Receiver for Windows 3.4 Cumulative Update 4 (3.4.400)

Compared to: Citrix Receiver for Windows 3.4 Cumulative Update 3

Receiver for Windows 3.4 Cumulative Update 4 (3.4.400) contains all fixes that were included in Receiver for Windows 3.4 Cumulative Updates 1 , 2, and 3 (3.4.100, 3.4.200, and 3.4.300), Receiver for Windows 3.4, 3.3, 3.2, 3.0, and the following, new fixes (no fixes were included in Receiver for Windows 3.1):

Content Redirection	Session/Connection
HDX MediaStream	System Exceptions
Logon/Authentication	User Experience
Printing	User Interface
Server/Farm Administration

Content Redirection

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]
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]
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]
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

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

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]
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

Automatic creation of printers is limited to 100 per session.

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

Server/Farm Administration

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

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]

[From RcvrforWin3.4_13.4.400][#LC0323]
COM port redirection can fail with the following error message:

"Error in OpenPort: Comport 'COM4'"

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

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

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.

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.

Custom seamless applications can truncate child windows where the child windows overlap the parent window after retaking focus from a local window.

[#236305]
With a smart card removal policy configured to disconnect a session upon removal of the smart card, Pnamain.exe can spike the server CPU when you remove the smart card from a pass-through session on the client device. Customers have also reported instances where disconnecting the session or closing the application will also cause Pnamain.exe to spike the CPU.

[#237003]
With TWAIN redirection enabled, a Cerner application fails to acquire images from a USB camera.

[#252136]
When you establish an RDP connection to the primary monitor of a dual-monitor endpoint device connected to a full-screen Virtual Desktop session that spans both screens and has the Desktop Viewer located on the secondary screen, the Desktop Viewer is not repositioned to the primary monitor within the RDP session.

[#255026]
In certain configurations involving Special Folder Redirection and a Citrix GPO configured to enable client drive mapping, the plug-in can exit unexpectedly.

[#257318]

[#257405]
When using a custom Delivery Services Console as described in Knowledge Center article CTX126752, the following can be observed:
- Client-side seamless application windows can get corrupted when moved or resized after the shadowing stops.
- Mouse operations can be erratic when shadowing is stopped and then resumed; specifically, the mouse pointer appears to be parked in the top left corner of the session window and immediately returns to that general area after attempting to move it.
Note: To address this issue in its entirety, you must install both a server and a client hotfix that contains Fix #258866.

[#258866]
In certain configurations, the Connection Center link can be disabled in the Citrix Receiver menu, or display incorrect data.

[#259193]

[#259772]
When running Dynamic Printer Discovery on a client against a server that does not support the feature and no printers are created on the client, published application launches can experience delays of up to 10 seconds.

[#260823]
Certain custom hotkeys do not work in Desktop Viewer sessions.

[#260921]
Dynamic Printer Discovery can lead to a noticeable amount of additional network traffic as client devices monitor for printer changes. This fix applies a different API to prevent additional network traffic.

[#LA0077]
When using a roaming profile and launching a published application the second time, the icon changes to low resolution.

[#LA0099]
When client-side IME input method is enabled for the client (wfica32.exe /LocalIME:On), and a local, client-side IME language bar is enabled as well, the local, client-side IME language bar is not visible when the ICA session has focus.

[#LA0133]
Using the pass-through client to launch an application published on the same server as the client creates an additional session if the domain name contains a period (.).

[#LA0297]
Hotkeys - for example, the Ctrl+F1 combination - do not work in virtual desktop sessions if the Desktop Viewer is enabled.

To enable this fix:
1. Set the following registry key:
  - On 32-bit Windows:
    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Client Engine\Hot Keys
    Name: AllowHotkey

  AllowHotkey=1
[#LA0303]
When using remote assistance software to shadow a Windows XP XenDesktop desktop viewer session with an odd (non-even) horizontal resolution, the shadowing window is skewed.

[#LA0313]
Applying Group Policy/Client Selective Trust settings to restrict the HDX File Access/Microphone permissions does not cause the related options in the HDX tab of Desktop Viewer Preferences to be disabled. Setting the InstantiatedSecurityPolicyEditable registry key to "false" as described in the procedure in Knowledge Center article CTX128792 disables those options in the Connection Center. After applying this fix, performing the same procedure also disables the options in the online plug-in user interface.

[#LA0358]
Attempts to connect to published applications from the Web Interface through the Secure Gateway can fail.

[#LA0445]
Full-screen videos are stretched to fill the entire screen regardless of aspect ratio.

[#LA0485]
With Browser Acceleration enabled, attempts to open a Sharepoint site with a GIF image on it can cause Windows Internet Explorer to exit unexpectedly. To address this issue in its entirety, you must install both a client and a server hotfix that contains Fix #LA0496.

[#LA0496]
Version 3 of the Citrix Receiver for Windows can experience above normal CPU utilization (10-20%) on wfica32.exe when multiple ICA sessions are initialized concurrently.

[#LA0522]
During a XenDesktop or XenApp session, the wfica32.exe process can consistently consume up to 15% of the CPU on devices (physical or virtual) with an AMD CPU.

[#LA0621]
Server-Side Content Fetching can exhibit poor performance in restrictive WAN conditions due to the lack of flow control in the Flash Virtual Channel. This fix corrects the flow control for the Flash Virtual Channel and provides smooth playback of Flash objects. For information about configuring server-side content fetching, see http://support.citrix.com/proddocs/topic/xendesktop-als/hd-flash-configure-server-ad.html.

Note: To address this issue in its entirety, you must install hotfixes that contain Fix #LA0686 for each of the following:
- Citrix Receiver
- Virtual Desktop Agent
- HDX MediaStream for Flash
[#LA0686]
With Session Reliability disabled and a session disconnect timer configured on the Virtual Desktop Agent as described in Knowledge Center article CTX117446, disconnecting a client session by clicking the Close (X) button of the session window or the Disconnect button on the Desktop Viewer causes the session to be treated as dropped rather than as gracefully disconnected. This prevents the session from assuming a disconnected state after the amount of time configured in the session disconnect timer. Instead, the session can linger in a Reconnecting state until Auto Client Reconnect stops listening for reconnection attempts. The default value for this is 300,000 ms (5 minutes).

[#LA0756]
This fix prevents seamless session windows from losing focus after a while. To enable it, you must add the following entry to the [WFClient] section of the appsrv.ini file and then restart the plug-in:

DisableReceiver=TRUE

[#LA0773]
TWAIN devices, such as scanners, might no longer be displayed and available in a session..

[#LA0784]
With the Desktop Appliance Lock installed, if multiple logon methods are specified on the Web Interface site and smart card authentication is specified as the preferred method, users cannot change their authentication method to connect to XenDesktop because no user interface is present for that purpose. With this fix, if no smart card is present in the reader, the default logon method switches to the first non-smart card method configured.

[#LA0805]
When enabling SpeedScreen Latency Reduction and both the Enable local text echo and Enable mouse click feedback server properties using the SpeedScreen Latency Reduction Manager tool, the mouse cursor can be missing from certain Web forms in high latency connections to the server.

[#LA0811]
Both the Receiver icon and the online plug-in icon appear in the notification area. This can be observed either after upgrading Online Plug-in 12.0.36 to Receiver 3.0 or fresh installation of Receiver 3.0 or Receiver 3.1 for Windows.

Note: When using the Merchandising Server to deploy the package, the latest version of the Citrix Receiver Updater must be used.

[#LA0858]
Copying and pasting content within Microsoft Excel 2010 running on Version 5.5 of the Virtual Desktop Agent causes the session to temporarily disconnect. The issue occurs when hovering the mouse pointer over the Paste Special menu option in Microsoft Excel 2010.

[#LA0911]
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]
With the option selected to refresh the application list when resources are accessed on a Web Interface site, the application list can fail to refresh.

[#LA1020]
The Windows 7 Snap-to mouse pointer option (Mouse Properties > Pointer Options > Snap To) does not work in XenDesktop sessions using Citrix Receiver for Windows 3.0.

[#LA1065]
Copying content from a published application to a local application can be delayed by several seconds.

[#LA1115]
When a user has prelaunch applications assigned and connects to a published desktop with Citrix Receiver pointing to the local client device, the desktop session disconnects immediately when the Application List is refreshed on the receiver within the desktop session.

[#LA1244]
With the Desktop Viewer enabled, 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.

[#LA1257]
While launching a published application in a pass-through session, the explorer.exe process can exit unexpectedly.

[#LA1396]
Audio playback from playlists can intermittently stop.

[#LA1485]
This fix provides an improved user experience with Internet Explorer 9 and Citrix Receiver.

[#LA1931]

Receiver for Windows 3.0

Compared to: Online plug-in 12.1

Receiver for Windows 3.0 contains the following fixes compared to online plug-in 12.1:

When connecting from a XenServer client virtual machine, a security dialog appears, asking permission to access a USB device, even if no USB devices are connected.

[#224646]
The audio volume in virtual desktop sessions can be inconsistent. Specifically, the client audio volume setting can take precedence over the equivalent setting on the Virtual Desktop Agent.

[#232926]
On certain client devices, using the automatic client download feature to install the online plug-in from Web Interface can cause Internet Explorer to become unresponsive instead of redirecting users to the Web Interface logon page.

[#234253]
Users with roaming profiles can encounter the following error message: "All components contained in this installation package are already installed. Click OK to exit installation" and attempts to launch applications fail.

The issue occurs when a roaming user makes connection attempt A from client device A where there is no Web client installed and then makes a connection attempt B from client device B where there is also no Web client installed. Connection attempt A causes the Web client to be installed on device A as expected. However, when the user makes connection attempt B, it is erroneously assumed that the Web client is also installed on device B, which is not the case. Consequently, no attempt is made to install the Web client on device B, and attempts to launch applications from device B fail.

[#234723]
When the Windows logon takes a long time due to, for example, Active Directory authentication, a full-screen published desktop does not display a status indicator to provide status feedback. This can be confusing to users. This fix modifies the behavior of the status indicator so that the indicator remains visible until the authentication completes.

Note: To correct this issue in its entirety, you must install both a server hotfix and a plug-in hotfix that contains Fix #235374.

[#235374]
With five or more sessions connected to particular server, additional connection attempts to the same server fail and the following error message appears: "Insufficient system resources exist to complete the requested service." To enable this fix, must set the following registry key:

HKEY_LOCAL_MACHINE\Software\Citrix\PNAgent
Name: FileBasedApplicationModel
Type: REG_DWORD
Data: 1

[#236159]
As of Versions 11.2 of the online plug-in and 11.1.003 of Desktop Receiver, a new default behavior (#208294) for full-screen hosted sessions has been in place to where in multiple monitor configurations local applications can no longer be positioned in front of the hosted session. This enhancement introduces support for a registry setting that lets you revert to the previous behavior that allows you to position local applications in front of the hosted session. To implement this change on the client side, set the registry key "TopMostOnFullScreen" as "False" under "HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Seamless Windows." To implement this enhancement from the server side, add the following line to the [WFClient] section of the default.ica file on the server:

"TopMostonFullScreen=off/False"

default.ica is located at:
- For Web Interface sites: C:\Inetpub\wwwroot\Citrix\XenApp\Conf\default.ica
- For the online plug-in: C:\Inetpub\wwwroot\Citrix\PNAgent\Conf\default.ica
[#236882]
After locking and unlocking a client device running Windows 7 64-bit Edition, some published applications are not positioned correctly.

[#237768]
On client devices running Microsoft Windows XP, pressing the Alt+Tab key combination within a full-screen published desktop session that is configured to use Windows keyboard shortcuts locally and not using Desktop Viewer fails to switch to locally running applications. Instead, you must press Alt+Tab twice.

[#239000]
Version 12.x of the plug-in can fail to launch applications. The issue occurs for non-administrative users in scenarios where the AlwaysInstallElevated policy is enabled and the CitrixOnlinePluginWeb package is installed on a per-user basis rather than on a per-device basis. In this scenario, some registry entries are created under HKLM and others under HKCU (as the installation is launched with elevated privileges). As a result, applications fail to launch.

[#239382]
With HDX MediaStream for Flash enabled, pressing Ctrl+A to select the Flash content on a Web page can cause any of the following:
- Windows Internet Explorer exits unexpectedly
- The cursor stops responding
- The Virtual Desktop Agents becomes unresponsive until it is restarted
[#239905]
When accessing a published desktop, applications that are configured as streamed to server and with offline access enabled start automatically when the online plug-in starts or online plug-in settings are refreshed.

[#240099]
Certain USB devices attached to a Virtual Desktop Agent can render the endpoint device unresponsive when the endpoint device goes into standby and/or hibernation mode.

[#240506]
After resizing a published desktop to full screen, pressing the Windows key opens the Start menu of the client device.

[#241308]
The wfica32.exe process can exit unexpectedly when launching multiple seamless applications through a proxy.

[#241718]
Security messages configured to appear when logging on to a server running XenApp 6 can obstruct the session launch progress indicator. This fix also addresses an issue where users connecting to a non-maximized desktop session cannot not see a progress bar on the client side.

[#243225]
While launching within a published desktop, the online-plug-in can become unresponsive.

[#244975]
Bitmap caching by way of a Group Policy does not take effect.

[#245043]
The pnamain.exe process can exit unexpectedly in multiple processor environments.

[#245626]
While in an ICA or Virtual Desktop session, pressing certain keys when the local operating system has focus can have the same effect as if the Windows key was pressed in combination with the that key. For example, pressing e launches Windows Explorer, as if the Windows key+e was pressed.

Note: This fix replaces Fix #211067.

[#246978]
When opening a client mapped serial port, invoking Flash redirection by visiting a Web site with Flash content, and closing the port, the serial port cannot be reopened.

[#248297]
With the Desktop Appliance Lock installed, if multiple logon methods are specified on the Web Interface site and smart card authentication is specified as the preferred method, users cannot change their authentication method to connect to XenDesktop because no user interface is present for that purpose. With this fix, if no smart card is present in the reader, the default logon method switches to the first non-smart card method configured.

[#248299]
Disabling audio queuing as a means of preventing multiple Microsoft Outlook appointment reminders from sounding at the same time (as described in Knowledge Center article CTX118453) can cause sound to be inaudible in the client session and the ctxsvchost.exe process to spike the CPU.

[#248470]
When the subscribing virtual machine establishes an ICA session with the publishing virtual machine, the user is required to enter credentials for the publishing virtual machine. The Windows authentication screen that appears on the subscribing virtual machine fails to get keyboard focus.

[#251019]
Desktop shortcuts to published applications can take a long time to recreate after refreshing the list of published applications. The issue occurs because as of Version 12.0 of the plug-in, the location of the icon cache was changed from the Roaming App Data to the Local App Data folder. This fix introduces support for the following registry that, if set, prevents the plug-in from repopulating the full icon cache when refreshing applications:

HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\PNAgent
Name: UseRoamFolder
Type: REG_DWORD
Data: 1

[#252526]
After upgrading to version 12.1 of the online plug-in, an SSL Error 40 can occur when attempting to connect to a server through the Secure Gateway and a proxy.

[#252861]
Setting ConnectionBar=1 in one or more [PublishedApplication] sections of the default.ica file causes the connection bar to be present in all applications running in the session â?? not just in the applications specified in the .ica file.

[#254235]
Even if only a single client certificate is installed, you are prompted to select a client certificate to use. With this fix, Internet Explorer's zone-specific setting "Don't prompt for client certificate selection when no certificates or only one certificate exists" is honored if set.

[#254481]
Custom applications that query the COM port's supported baud rate capability can fail when the rate is set at speeds above 9,200 baud.

[#254605]
After unlocking a virtual desktop session with a USB device attached to the client device, the Desktop Viewer can be unresponsive.

[#254624]
Attempts to launch applications can fail if the DNS aliases for XenApp servers contain underscores ("_").

[#255331]
Disabling short file names by setting HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem\NtfsDisable8dot3NameCreation=1 can cause sessions to fail to launch.

[#255592]
On client devices running Microsoft Windows 7, the online plug-in does not detect the Internet over UMTS WAN connections.

[#255859]
When using the online plug-in in pass-through mode, vdcdm30n.dll can cause the wfica32.exe process to exit unexpectedly while attempting to access mapped client drives.

[#256868]
When using a batch file to create printers, printers fail to autocreate if there are printer name mismatches.

[#258044]
After upgrading a client device with Version 12.1 of the online plug-in installed to Windows Internet Explorer 9, attempts to launch applications from the Web Interface fail and a "Sharing Violation" error occurs. The issue occurs because Internet Explorer cannot access the cached ICA file.

[#259548]
If the name of a published application contains an ampersand (&), refreshing applications from the notification area indicates that the plug-in does not have connectivity even though it does.
