Citrix Quick Launch has been written to offer some features of the legacy Citrix Program Neighborhood for users of the Citrix Online Plug-in and Citrix Receiver releases. While it will also work with older releases, its purpose is to be used in conjunction with Citrix Online Plug-in version 11.2 and later.

Installing Citrix Quick Launch

  1. Extract the contents of the zip file to a folder.

Note: This tool was tested to create ICA sessions against Citrix Presentation Server 4.0, XenApp 4.5, XenApp 5.0 for Windows 2003, XenApp 5.0 for Windows 2008 (32-bit and 64-bit editions), XenApp 6.0 for Windows Server 2008 R2, XenApp 6.5 for Windows Server 2008 R2 and XenDesktop 5.x in HA mode from workstations running Windows 2000, Windows XP, Windows Vista and Windows 7 and Windows 8 (32-bit and 64-bit edition).

While the tool might work with legacy Citrix server releases (such as MetaFrame Presentation Server 3.0, MetaFrame XP, MetaFrame 1.x), it has not been fully tested.

How to Use Citrix Quick Launch

When running the Citrix Quick Launch tool, you can specify the server name or IP address. The tool offers a drop-down list where you can select a previous server

The following actions are then possible:

  1. Click Connect… to initiate an ICA session to this server.
  2. Click Options >> to access additional features.

When the Options button is clicked, the tool offers additional features to configure.

Note: When running on a machine with a Citrix Online Plug-in version 11.2 or later, UDP Browsing has been removed from this release therefore the only browsing protocol available if TCP/IP over HTTP. The XML Service port needs to be specified. More information can be found in CTX123616 - ICA Client Object Changes in the Version 11.2 XenApp Plug-in


The tool offers the possibility to connect directly to the server’s desktop (default setting when the Options are not displayed) or a published application in the farm.

To browse the published applications, the correct browsing mechanism should be selected (refer to the note above for Citrix Online Plug-in version 11.2 and later).

In the case of XML Browsing, make sure the XML Service port is correct.

Note: the option “Launch on this server” (when selecting a published application) will bypass the load balancing mechanism by directly connecting to the XenApp server specified in the “Server” field above.

When a published application is selected, the engine uses seamless mode by default while the ICA session is started in a fixed size window if connecting to a server’s desktop.

Within this General tab, you can launch the ICA session and also save the settings which will create a specific icon for that connection in the Connection tab. It is also possible to generate an ICA file based on the current displayed settings.

    • Using the tool with XenDesktop 5 High Availability Mode

When selecting the XenDesktop 5 option, the below warning is presented :

More information about this mode can be found in CTX127564 - How to Implement High Availability Features in XenDesktop 5

    • Features

Several features can be enabled/disabled from the Session Options tab:

The tool will use the same default settings as Program Neighborhood did. The local drives and printers are available inside the session, based on the configuration of the Citrix Policies.

Note: The Citrix Desktop toolbar (Desktop Viewer) is disabled, by default.

Some SpeedScreen Latency Reduction features can be configured in the SpeedScreen tab.

The hotkeys can be configured in the hotkeys tab :

    • Custom connections

The tool supports the creation of custom connections via the Connection tab

Similar to the Custom ICA Connection settings from Program Neighborhood, you can create, edit, rename and launch connections to different farm, servers and applications. Note: the settings are independent from the other tabs

When the tool is closed, the servers’ names, XML port, username, domain, selected options (such as display resolution, color choice, encryption, modified hotkeys...) are saved in the registry in HKEY_CURRENT_USERSoftwareCitrixCitrixQuickLaunch.

Command Line arguments

The Citrix Quick Launch tool supports command line arguments to connect directly to a server or a published application over an ICA session, without displaying the user interface, using default settings for the ICA session.

1. To connect to a server without the user interface, run the command below:

citrixquicklaunch.exe /s:<servername>


<servername> is the name or IP address of your XenApp server

The session initializes inside a 1024x768 window, using 24-bit color depth. Printers and drives are autocreated, based on the configuration of Citrix Policies. No specific encryption setting can be used.

2. To connect to a published application without the user interface, run the command below:

citrixquicklaunch.exe /s:<servername>:<XMLport> /a:<name of published application>


<servername> is the name or IP address of your XenApp server.

<XMLport> is the XML server port number of the XenApp server (not required if the default TCP 80 port is used)

<name of the published application> is the name of the published application you wish to connect to.

The name does not need to be enclosed within quotation marks. It is important to write carefully the name of the published application, otherwise the ICA session fails to launch. The published application starts inside a seamless session, using 24-bit color depth. Printers and drives are autocreated, based on the configuration of Citrix Policies. No specific encryption setting can be used.

3. To launch a session using an existing connection, run the command below :

citrixquicklaunch.exe /q:<connection>


<connection> is the name of a saved connection as displayed in the “Connections” tab

4. To enable passthrough authentication from the command line, run the command below :

citrixquicklaunch.exe /sso


this switch can be used with any of the above switches.

The generally recommended packet loss metric to support VoIP is 0.5 percent or less. However, depending on customer expectations, higher packet loss might be acceptable.

(Results with jitter at ten percent of one-way latency ‑ E = Excellent; G = Good; F = Fair, P = Poor)
The XenDesktop 4 release does not include jitter buffering. High levels of VoIP jitter over the ICA connection from the user to the Virtual Desktop Agent platform can result in bad call quality or delay in the conversation.

Field Evaluation

In addition to the testing performed by Citrix in the lab, an evaluation was done at a customer location. The testing was done with Wyse and HP thin clients running Windows XPe or Windows Embedded, regular PCs running Windows XP, and with Logitech and Netcom USB headsets.
On the LAN, isochronous USB redirection was used. The softphone performed “perfectly”. The voice quality was judged to be “essentially just as good as that provided by a physical Cisco handset.”
Testing with at-home workers was done using typical ADSL2 network connections ranging from 2 megabits per second to 20 megabits per second down, and 0.5 to 1.0 megabits per second up. The Optimized-for-Speech codec was used. The voice quality was judged to be “great” and “perfectly usable”.
Without voice energy detection (discarding of low-energy “silent” packets), latency on congested WAN connections can become excessive. Voice energy detection was introduced as a hotfix enhancement and is included in XenDesktop 4 Virtual Desktop Agent Update 2 (which is part of XenDesktop 4 Feature Pack 1).

Enhanced 911

Enhanced 911 might not be functional when CIPC is streamed to the virtual desktop. Streaming of CIPC was tested with a prior release of the Citrix application streaming technology (client-side virtualization) which did not support Windows services. Therefore, one of the steps described in this article is to disable the use of CDP by the Cisco IP Communicator if the softphone is streamed to the virtual desktop. The Enhanced 911 implementation in IP Communicator has a dependency on CDP. Therefore, disabling CDP also disables Enhanced 911.
