Last Updated: 15 September 2016

These release notes cover the following topics:

Key Features

HTML Access makes it easy to access your Horizon virtual desktops (Windows and Linux) and applications from an HTML5-based browser. No need to install any software.

  • Work the way you want to - Access View desktops and applications from device platforms where no native client is available, or from any computer on which you do not want to install software. You can also select HTML Access from a VMware Workspace Catalog.
  • Simple connectivity - HTML Access is tightly integrated with VMware Horizon 7 for simple setup and connectivity. Open a browser, enter a server URL, and log in to see a list of available View desktops and applications.
  • Secure from any location - At your desk or away from the office, your data is always secure. Enhanced certificate checking is performed on the client. HTML Access also supports optional RADIUS and RSA SecurID authentication.

What's New in This Release

  • Time zone synchronization
    When you connect to a remote desktop with HTML Access, the desktop displays time in your local time zone. This feature is automatically configured for virtual machine desktops. For RDS desktops, an administrator must enable time zone synchronization by setting the Time Zone Redirection group policy setting. For more information, see "Enable Time Zone Redirection for RDS Desktop and Application Sessions" in Setting Up Desktop and Application Pools in View.
  • Remove credentials from cache
    An administrator can configure View to remove a user's credentials from cache when a user closes a tab that connects to a remote desktop or application, or closes a tab that connects to the desktop and application selection page. For more information, see "Configure View to Remove Credentials From Cache" in Using HTML Access.
  • Spanish language support
    Both the HTML Access user interface and the documentation are now available in Spanish.

Known Issues

  • On iOS Safari, if you connect to a remote desktop and play audio or video on the desktop, and switch to playing audio or video with a native application without disconnecting from Connection Server, and switch back to the remote desktop on Safari, audio will no longer work.
    Workaround: Disconnect or logoff from Connection Server and connect to the desktop again.
  • HTML Access is supported on iOS devices but not on Android and other mobile devices for this release.
  • When you use any version of HTML Access with Firefox 40, 41, or 42, audio does not work. Note that these versions of Firefox are not supported by any version of HTML Access.
    Workaround: Use a supported version of Firefox.
  • The location-based printing feature does not work if you set your browser to use a proxy or if the client system is in a vLAN that is different from the vLAN in which the View environment is located.
  • Location-based printing policies that use the Mac Address or client name are not supported.
  • 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 and Windows Server 2012 R2 RDS hosts. The printers shown within applications are correct, however.
    Workaround: Log off the desktop running on the server and reconnect to it.
  • VMware recommends not using RDS Per Device Client Access Licenses (CALs) for HTML Access. If you do so, the licensing mechanism treats each browser as a device, and if cookies are cleared, the browser will use another license.
    Workaround: Use RDS Per User CALs for HTML Access.
  • Sound playback quality is best on browsers that have Web Audio API support. Chrome, Safari, and Firefox 25 and later browsers have Web Audio API support. Browsers that do not have this support include Internet Explorer (up to and including Internet Explorer 11) and Firefox 24 and earlier.
  • On Chrome browsers, if audio is playing and you switch to another tab in the browser, audio processing becomes intermittent. After you re-focus on the View desktop tab, audio might be out of sync with video for a few seconds.
    Workaround: Either refresh the page or pull the View desktop's tab out of the browser so that it has its own window.
  • The Linkclump Google Chrome extension interferes with proper right-click behavior. If you right-click something in the remote desktop, you might see the right click behave like a left-click-and-drag action.
    Workaround: Either disable the extension or go into the Google Chrome browser's Linkclump Options page and in the Blacklist section, enter the address of the View Connection Server.
  • If you are using a Firefox browser and your HTML Access desktop session gets disconnected immediately upon connecting, verify that your Firefox browser proxy settings are configured correctly.
  • Do not configure desktops to be suspended after users disconnect. This setting does not work correctly with HTML Access.
  • Connecting to a desktop or application fails if Blast Secure Gateway (BSG) is enabled on both the Access Point server and the View Connection Server.
    Workaround: Disable BSG on the View Connection Server.
  • In Access Point, if you set the View Edge Setting "blastEnabled" to False, you will not be able to access remote desktops and applications through HTML Access. Generally, because Access Point is deployed in a DMZ, the "blastEnabled" option is set to True, and this issue does not occur.
    Workaround: In Access Point, if you set "blastEnabled" to False and also use HTML Access, you must also set the "proxyPattern" option to "/|/portal(.*)".
  • If you try to connect to a VADC (View Agent Direct Connection) desktop or application using Internet Explorer, Safari, or Firefox, and you click Cancel on the login page, the login button will be disabled, although you can still enter a user name and password. If you click Cancel again, the login button will be enabled, but logging in with a valid user name and password will fail and you will be presented with the login page again.
  • When you connect to a Linux desktop with the Japanese keyboard, the keyboard mapping might be incorrect. For example, the key positions \| and \_ will be incorrect.
    Workaround: Keep the client input language as Japanese and switch the desktop input language to English for the two key positions \| and \_ only. Keep the desktop input language as Japanese and switch the client input language to English for all other key positions.
  • When connecting to a Linux desktop, some keyboard input does not work. For example, (1) with English keyboard, the * key on the numeric keypad is display as 8, (2) with English keyboard, the + key on the numeric keypad is displayed as =, and (3) with non-English IME on both client and desktop, some non-English keys are not displayed correctly.
    Workaround: For issues #1 and #2, use the typewriter keys * and + in the main keyboard area instead of the numeric keypad. For issue #3, set English IME on the HTML Access client and non-English IME on the desktop.
  • With Safari 9 and with Blast Secure Gateway (BSG) disabled, when a user launches a desktop for the first time, a gray blank screen appears instead of the desktop. If the user closes the session by clicking the Close button on the sidebar and reconnects to it by clicking the desktop on the sidebar, the desktop launches correctly but the logoff function will not work and will cause the desktop window to freeze. This issue only happens the first time the user launches a desktop.
    Workaround: Close the Connection Server session by logging out of the Connection Server or by closing the browser, and log in to the Connection Server again.
  • After Horizon 7 is upgraded from 7.0 to 7.0.1, users who have previously connected to a version of Horizon that is older than 7.0.1 do not see the new feature RTAV or File Transfer.
    Workaround: Perform one of the following actions:
    • Clear the browser's cache before logging in to the Connection Server.
    • Launch a desktop and refresh the browser.
  • Intermittently, autofit of an application does not work. This can happen if you launch an application and then activate full-screen mode for the browser, or launch an application from the sidebar and activate full-screen mode, or launch an application and then enlarge the size of the browser window.
    Workaround: Activate full-screen mode or resize the browser window before launching an application.
  • On ChromeBook, when connecting to an Access Point server that uses a self-signed certificate, HTML Access reports the error ERR_CERT_INVALID.
    Workaround: Install a CA-signed certificate on the Access Point server.
  • With Chrome version 50 or later, using the RTAV feature sometimes causes Chrome Tab to crash.
    Workaround: Close the Chrome Tab and start a new Tab to connect to the desktop again.
  • Users can still upload files when the remote desktop is locked.
    Workaround: None.
  • If you use HTML Access with Firefox 46, you might encounter problems.
    Workaround: Use a different version of the Firefox browser, for example, Firefox 47, or use a different browser.
  • On iOS 8, if you attempt to connect to a remote desktop using a self-signed certificate, Safari reports the error "Your desktop has been disconnected. Unable to reconnect to desktop." This problem occurs because self-signed certificates are not supported on iOS 8.
    Workaround: An administrator must install a CA-signed certificate on the View server and you must trust the certificate on your iOS 8 device. For information about installing certificates on a View server, see the View Administration document. For information about trusting certificates on an iOS device, see Using HTML Access. If the Blast Secure Gateway is disabled on the View server, an administrator must perform the following additional steps on the remote desktop to connect from iOS 8:
    1. Use mmc to import the CA-signed certificate into the Windows certificate store.
    2. Replace the sslHash key in HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware Blast\Config with the key from the thumbprint of the certificate issued to the Blast Agent Hostname or IP address.
    3. Restart the Blast Agent VM.
  • When the "Clean up credential when tab closed for HTML Access" global setting is enabled in View, the cache is not cleared if a user closes a tab when the network connection is not available.
    Workaround: None
  • When the "Clean up credential when tab closed for HTML Access" global setting is enabled in View, the cache is cleared if a user clicks the backward button in a remote desktop or application.
    Workaround: Log on to the Connection Server instance and connect to the remote desktop or application again.
  • When an administrator enables a clipboard format restriction, the text in the Copy & Paste window does not describe the format limitation. For example, if an administrator enables the "Filter text out of the incoming clipboard data" clipboard policy setting, the Copy & Paste window does not notify the user that text cannot be transferred from the client to the remote desktop or application.
    Workaround: None
