HTML Access Release Notes
HTML Access 4.5 | 8 June 2017
Last Updated: 15 June 2017
These release notes cover the following topics:
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
- Multiple-monitor support
If you use a Chrome browser (version 55 or later), you can add up to one additional monitor to your primary monitor to display the current remote desktop window.
- Bypass Web portal screen
End users can now select a new check box on the VMware Horizon Web portal screen to bypass the Web portal screen and take them directly to the Login screen.
- Support for Workspace ONE mode
When the Workspace ONE mode is enabled in the Connection Server Settings Authentication tab, end users can only connect to the Connection Server through the Workspace App Portal. They will be redirected to the Workspace App Portal portal when they try to connect to the server through HTML Access.
- Audio Out support
The HTML Access audio output support for Horizon 7 Linux Desktops is now available.
- Seamlessly launch remote applications
Remote applications are now launched seamlessly without the need to load and display the profile screen.
- Support unauthenticated access to remote RDSH applications
End users can connect to published applications using an unauthenticated access account with HTML Access.

Before You Begin
- For a list of the supported browsers, supported client operating systems, HTML Access system requirements, and installation instructions, see Using HTML Access.
- HTML Access 4.5 supports Horizon Agent 7.2.
- With HTML Access 4.5 and Horizon 7.2, if you connect to Connection Server through a load balancer or a gateway such as F5 or Unified Access Gateway (previously Access Point), you must first configure a security setting in View. For more information, see "Origin Checking" in View Security.

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,
42, or 50.0, 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
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
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.
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.
Chrome, Safari, and Edge browsers, if audio is playing and you
switch to another tab in the browser or minimize 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.
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
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.
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
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.
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(.*)".
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
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
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.
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.
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 or a later version, 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.
Perform one of the following actions:
- Clear the browser's cache before logging in to the
- 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
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.
Install a CA-signed certificate on the Access Point server.
Users can still upload files when the
remote desktop is locked.
If you use
HTML Access with Firefox 46, you might encounter problems.
Note Firefox 46 is not a supported version.
Use a supported version of the Firefox browser, for example,
Firefox 47, or use a different browser that is supported.
- On iOS, 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.
Workaround: An administrator must install a CA-signed certificate on the View server and you must trust the certificate on your iOS 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:
- Use mmc to import the CA-signed certificate into the Windows certificate store.
- 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.
- 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
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.
If you access a remote desktop or application through HTML
Access that is connected via an Access Point server, the
remote desktop or application session does not get
disconnected after the Access Point server session timeout is
Occasionally, RTAV video redirect does not work when using it
for a second time with Chrome on a Mac OS system.

using Horizon View that is connected via an Access Point
server, using the URI format "
in a Web browser results in the following error:
"This <AP-Address> page can’t be found. No
webpage was found for the web address: https://<AP-Address>/?domainName=finance&userName=fred",
where <AP-Address> is the IP or FQDN of the
Access Point server."
Modify the URI format by adding "
after the <AP-Address> part. For example, use
- On Internet Explorer 11.0.9600.18537 or earlier, prior to logging into a VMware Blast session, if the user launches an HTML Access Agent that does not have a certificate, a certificate confirmation page appears. After confirming the certificate, the user is returned to the desktop and application selection page instead of the Blast session page.
Workaround: On the desktop and application selection page, click the desktop again and the connection will succeed.
After a user connects to an HTML Access Agent and opens an
Internet Explorer 11 or Edge browser, attempts to resize the
browser window fails.
Use a Firefox or Chrome browser instead.
While using Safari 10.1 to upload a file, the reconnect dialog box pops up. The file transfer is interrupted and sometimes the remote session will be disconnected. This a known Safari bug: https://bugs.webkit.org/show_bug.cgi?id=170463
Workaround: Use a Firefox or Chrome browser instead.
After an administrator sets the 'change password at next logon' option for a user's account and the user's idle session times out, the application that was active during the session timeout is not re-launched automatically after the user re-authenticates and changes the password successfully.
Workaround: Refresh the page and launch the application again from the sidebar.
On a Chrome 59 browser, the password text box displays the entered password as plain text, instead of masked text, under the following scenarios:
- Prior to using HTML Access, the end user cleared the Chrome 59 browser history or reset the browser to have the original default settings.
- The end user uses HTML Access for the first time on a newly installed Chrome 59 browser.
Workaround: Refresh the browser page.
