The following table describes the Horizon Client installation properties.

Horizon Client Installation Properties
Property	Description	Default
`INSTALLDIR`	Path and folder in which Horizon Client is installed. For example: `INSTALLDIR=""D:\abc\my folder""` The sets of double quotes that enclose the path enable the installer to interpret the space as a valid part of the path.	`application folder nested under %ProgramFiles%`
`VDM_IP_PROTOCOL_USAGE`	IP (Internet Protocol) version that Horizon Client components use for communication. Valid values are as follows: IPv4 IPv6 Dual If you specify Dual, Horizon Client checks the current network and connects over IPv4 or IPv6 automatically.	IPv4
`VDM_FIPS_ENABLED`	Determines whether to install Horizon Client with FIPS-compliant cryptography. A value of 1 installs Horizon Client with FIPS-compliant cryptography. A value of 0 installs Horizon Client without FIPs-compliant cryptography. Note: Before you set this property to 1, you must enable FIPS mode in the Windows client operating system. See Enabling FIPS Mode in the Windows Client Operating System.	0
`VDM_SERVER`	Fully qualified domain name (FQDN) of the Omnissa Horizon Connection Server instance to which Horizon Client users connect by default. For example: `VDM_Server=cs1.companydomain.com` You can specify multiple server instances separated by semicolons. If you configure this property, Horizon Client users do not need to supply this FQDN.	None
`LOGINASCURRENTUSER_DISPLAY`	Determines whether Log in as current user appears in the Options menu on the Horizon Client menu bar. Valid values are 1 (enabled) or 0 (disabled).	1
`LOGINASCURRENTUSER_DEFAULT`	Determines whether Log in as current user is selected by default in the Options menu on the Horizon Client menu bar. Valid values are 1 (enabled) and 0 (disabled). When log in as current user is the default login behavior, the identity and credential information that users provide when they log in to the client system is passed to the Horizon Connection Server instance and ultimately to the remote desktop. When log in as current user is not the default login behavior, users must provide identity and credential information multiple times before they can access a remote desktop or application. Note: If you change this value for the user interface, Horizon Client ignores the related default group policy setting.	0
`ADDLOCAL`	Specifies the features to install. Valid values are as follows: `ALL` - Installs all available features, except for URL Content Redirection. `TSSO` - Installs the Log in as Current User feature. `USB` - Installs the USB Redirection feature. To specify individual features, enter a comma-separated list of feature names. Do not use spaces between names. For example, to install Horizon Client with the USB Redirection feature, but without the Log in as Current User feature, type the following command: `Horizon-Client-y.y.y-xxxxxx.exe ADDLOCAL=USB`	None
`INSTALL_SFB`	Determines whether the Virtualization Pack for Skype for Business feature is installed. A value of 1 installs the feature. A value of 0 does not install the feature.	1
`INSTALL_HTML5MMR`	Determines whether the Support for HTML5 Multimedia Redirection and Browser Redirection feature is installed. A value of 1 installs the feature. A value of 0 does not install the feature.	1
`REMOVE`	Specifies the features not to install. Valid values are as follows: `Scanner` - Does not install the scanner redirection feature. `FolderRedirection` - Does not install the folder redirection feature. `SerialPort` - Does not install the serial port redirection feature. To specify multiple features, enter a comma-separated list of feature names. Do not use spaces between names. For example, the following command does not install the scanner redirection feature: `Horizon-Client-y.y.y-xxxxxx.exe REMOVE=Scanner`	None
`DESKTOP_SHORTCUT`	Determines whether to create a desktop shortcut for Horizon Client. A value of 0 does not create a desktop shortcut. A value of 1 creates a desktop shortcut.	1
`STARTMENU_SHORTCUT`	Determines whether to create a Start menu shortcut for Horizon Client. A value of 0 does not create a Start menu shortcut. A value of 1 creates a Start menu shortcut.	1
`URL_FILTERING_ENABLED`	Determines whether the URL Content Redirection feature is installed. A value of 1 installs the feature. A value of 0 does not install the feature. When you set this property to 1 in an interactive installation, the URL Content Redirection check box appears under Additional features on the custom installation dialog box and is selected by default. The check box does not appear unless you set this property to 1. Note: The `ADDLOCAL=ALL` property does not include the URL Content Redirection feature.	0
`AUTO_UPDATE_ENABLED`	Determines whether the online update feature is enabled. A value of 1 enables the feature. A value of 0 disables the feature. For more information, see Update Horizon Client Online.	1

Prerequisites

Verify that the client system uses a supported operating system. See Hardware and Software Requirements for Windows Client Systems.
Verify that you can log in as an administrator on the client system.
Verify that the domain controllers have the latest patches, enough free disk space, and can communicate with each other.
If you plan to install Horizon Client with FIPS-compliant cryptography, enable FIPS mode in the client operating system. See Enabling FIPS Mode in the Windows Client Operating System.
Decide whether to use the feature that allows end users to log in to Horizon Client and their remote desktop as the currently logged in user. Credential information that the user entered when logging in to the client system is passed to the Horizon Connection Server instance and ultimately to the remote desktop. Some client operating systems do not support this feature.
Become familiar with the Horizon Client installation commands.
Become familiar with the Horizon Client installation properties.
Determine whether to allow end users to access locally connected USB devices from their remote desktops. If not, set the ADDLOCAL installation property to the list of features and omit the USB feature.
If you do not want end users to have to supply the fully qualified domain name (FQDN) of the Horizon Connection Server instance, determine the FQDN so that you can supply it during installation.

Procedure

Log in to the client system as an administrator.
Navigate to the client downloads page Customer Connect.
Download the Horizon Client installer file, for example, Horizon-Client-YYMM-y.y.y-xxxxxx.exe.

YYMM is the marketing version number, y.y.y is the internal version number, and xxxxxx is the build number.
Open a command prompt on the Windows client computer.
Type the installer file name, installation commands, and installation properties on one line.

Horizon-Client-YYMM-y.y.y-xxxxxx.exe [commands] [properties]

Results

The installer installs Horizon Client according to the installation commands and properties that you specify. If you specify the /silent installation command, the wizard prompts do not appear.

The installer installs Windows services, including Horizon Client (horizon_client_service) and USB Arbitration Service (VMUSBArbService).

Example: Sample Installation Commands

The following command installs Horizon Client interactively and enables the URL Content Redirection feature.

Horizon-Client-YYMM-y.y.y-xxxxxx.exe URL_FILTERING_ENABLED=1

The following command installs Horizon Client silently and suppresses all restarts and restart prompts during the installation process.

Horizon-Client-YYMM-y.y.y-xxxxxx.exe /silent /norestart

What to do next

If you enabled the URL Content Redirection feature when you installed Horizon Client, verify that the feature is installed. See Verify URL Content Redirection Installation.

Start Horizon Client and verify that you can log in to the correct remote desktop or published application. See Connect to a Remote Desktop or Published Application.
