Key Features

VMware Horizon Client for Windows makes it easy to access your Windows or Linux virtual desktop or hosted Windows desktops and applications with the best possible user experience on the Local Area Network (LAN) or across a Wide Area Network (WAN).

  • Support for Windows 10, Windows 8 and 8.1 (with Updates), and Windows 7
  • Unmatched performance - The adaptive capabilities of the PCoIP display protocol and the Blast Extreme display protocol are optimized to deliver the best user experience, even over low-bandwidth and high-latency connections. Your desktop is fast and responsive regardless of where you are.
  • Simple connectivity - Horizon Client for Windows is tightly integrated with VMware Horizon 6 and Horizon 7 for simple setup and connectivity.
  • Secure from any location - At your desk or away from the office, your data is delivered securely to you wherever you are. SSL/TLS encryption is always used to protect user credentials, and enhanced certificate checking is performed on the client. Horizon Client for Windows also supports optional RADIUS and RSA SecurID authentication. You can also install Horizon Client for Windows so that the client runs in FIPS mode.

What's New in This Release

  • Full support of Flash Redirection
    For specific URLs, Flash content in an Internet Explorer browser is sent to the Windows-based client and played in a Flash container window, thereby offloading demand on the ESXi host. Configuration is done through group policy. This feature also requires Horizon Agent 7.0 or later.
  • Command-line interface enhancement
    Enhancement to Horizon Client's Command-line interface to allow the launcher to be visible after launching an application.
  • Automatic upgrade
    Horizon Client can be upgraded through the user interface.
  • Client device authentication
    The device that Horizon Client runs on can be authenticated.
  • Support for login as current user in a nested environment
    In a nested environment (Horizon Client running on a Horizon desktop and accessing another Horizon application or desktop), users can login as current user.
  • Launching multiple Horizon Client instances using URI
  • OpenSSL 1.0.2h support
    The OpenSSL library is updated to version openssl-1.0.2h.

Known Issues

  • After you install Horizon Agent 7.0.x in a Windows 7 or Windows Server 2008 R2 remote desktop, you can no longer use the Microsoft RDP display protocol to connect to the remote desktop. This problem occurs because TLSv1.0 is disabled by default in Horizon 7 version 7.0 and later.
    Workaround: Install Microsoft update 3080079: Update to add RDS support for TLS 1.1 and TLS 1.2 in Windows 7 or Windows Server 2008 R2 in the Windows 7 or Windows Server 2008 R2 virtual machine and in any Windows 7 client machines.
  • When attempting to use the Real-Time Audio-Video feature on a Surface Pro 4 device, you see only a black screen. This issue occurs because the client needs to be configured to accommodate the default screen resolution for a Surface Pro 4, which is 1920 X 1080.
    Workaround: On the Windows client machine, edit the following registry keys under HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\RTAV:
    • Set srcWCamFrameHeight to 1080.
    • Set srcWCamFrameWidth to 1920.
  • The serial port redirection group policy setting Bandwidth Limit does not set a limit on the bandwidth.
    Workaround: Use third-party software to limit the bandwidth.
  • With serial port redirection, at a high baud rate such as 115200, the performance of VMware Blast is significantly worse than PCoIP, and the connection might sometimes hang.
    Workaround: Use a baud ate of 9600.
  • In an IPv6 environment, if you configure IP address mapping for location-based printing, users might encounter a problem accessing the printer because the client can have multiple IPv6 addresses. Anytime the client connects, it can use any one of the addresses.
    Workaround: Use the location-based printing group policy setting IP Range to include the multiple addresses. However, the printing problem might still occur because the client might use a temporary address, which is not in the specified range.
  • If you use Horizon Client to connect to a remote desktop that has client drive redirection disabled, such as through a group policy setting, or if you connect to a remote desktop that has View Agent 6.1.0 or an earlier version installed, no message is displayed to explain why the client drive redirection feature is not working.
  • On Windows 7 and Windows Server 2008 R2 desktops, if you remove a drive from being shared on the desktop, Windows Explorer continues to display the removed drive in the guest operating system.
    Workaround: Close and reopen Windows Explorer.
  • On Windows 7 and Windows Server 2008 R2 desktops, if you open files in a shared folder on the desktop, disconnect from the desktop, and reconnect to the desktop, the left navigation pane in Windows Explorer displays duplicate entries for the shared drive.
    Workaround: Close and reopen Windows Explorer.
  • On Windows 7 client systems, you cannot use the Windows Media MMR feature with videos that use Dolby AC3 audio. On Windows 7 clients, Windows Media Foundation does not have the proper codec to support Dolby AC3 audio files. This issue does not occur on Windows 8.x clients.
  • In the Settings dialog box, pressing the Tab key has no effect.
  • Sometimes the virtual printing feature and location-based printing feature are not able to display the correct list of printers in the Devices and Printers window of a remote, session-based desktop. This issue can occur with desktops provided by Windows Server 2012 RDS hosts. The printers shown within applications are correct, however.
    Workaround: Log off the desktop running on the Windows Server host and reconnect to it.
  • Virtual printing might not work if you connect to a remote desktop using RDP, open Horizon Client on the remote desktop, launch a nested application session, and then log off and log back in to the desktop. When you try to print from the nested application, the expected printer list might not appear. This issue only occurs after you log back in to the desktop.
    Workaround: Reset the application on the remote desktop. To avoid having to set applications, use PCoIP for both ends of the session-in-session connection. That is, use PCoIP to connect to the remote desktop and use PCoIP to connect from within the desktop to the nested application. If you are using location-based printing, you can resolve this issue by closing and reopening the application's print dialog box.
  • If multiple Horizon clients connect to the same RDS desktop or remote application simultaneously and map to a location-based printer with the same name, the printer appears in the first client session, but not in later client sessions. This problem also occurs for client-redirected virtual printers.
    Workaround: For the client sessions in which the printer does not appear, perform a manual refresh. For a remote desktop, press F5 or refresh the Devices and Printers window. For a remote application, close and reopen the application print dialog box. The location-based printer appears in the printer list.
  • In a nested, or session-in-session, implementation of Horizon Client, the virtual printing feature works only for remote applications and not for desktops. An example of a session-in-session implementation is one in which an end user logs in to Horizon Client on a thin client, so that the Horizon Client interface is the only one the end user sees, and the end user then launches a nested version of Horizon Client in order to use a remote application provided by an RDS host.
  • If your client operating system is Windows 8.1 and you launch a Microsoft RDP session, pressing Ctrl+Alt+Insert does not send Ctrl+Alt+Del to the remote virtual desktop.
    Workaround: Upgrade the operating system by installing Windows 8.1 Update.
  • If you use a touch-enabled screen on your client system to work in a View desktop, do not use the Enable Relative Mouse feature. This feature provides improved mouse performance for 3D and CAD applications, but for touch-enabled screens and tablets, the mouse coordinates are not translated properly, even in 3D and CAD applications.
  • If you have multiple monitors with different screen resolutions and expand Horizon Client to all monitors and then select the Enable Relative Mouse feature, occasionally, the mouse pointer might not be able to move downward beyond a certain position.
    Workaround: Press Ctrl+Alt.
  • When a user connects to a desktop using PCoIP shortly after the desktop is powered on, autofit of the desktop window might not work. This issue happens most often if the desktop or network is under stress shortly after power-on (to start multiple applications or to map network drives, for example).
    Workaround: Double-click the desktop window's title to go into window mode and double-click the title bar to go into all-monitor mode.
  • On Windows 10, Windows Fax and Scan hangs when using a CardScan 800 device.
    Workaround: None.
  • When you use the Flash redirection feature to play a video, you cannot exit full-screen mode because the Exit Full Screen button does not appear in the Flash player toolbar.
    Workaround: Press Ctrl+Alt+Delete and unlock the client side to see the Horizon Client toolbar and then adjust the window size to
    make the Flash player window smaller.
  • When you use the Flash redirection feature to play a video, if you click the Ad link at the bottom of the screen or the More Info link in the Flash player, the advertisment page does not pop up and the playback pauses.
    Workaround: None.
