System Requirements for Chrome OS Devices
The device on which you install Horizon Client must meet certain system requirements.
Device models Chromebook
Operating systems Chrome OS, stable channel, ARC version 41.4410.244.13 or later
CPU architecture nARM
nx86
VMware, Inc. 7
Connection Server,
security server, and
View Agent or
Horizon Agent
Latest maintenance release of Horizon 6 version 6.x and later releases.
VMware recommends that you use a security server or
Unied Access Gateway appliance so that client devices do not require a
VPN connection.
Display protocols nPCoIP
nVMware Blast (requires Horizon Agent 7.0 or later)
System Requirements for Real-Time Audio-Video
Real-Time Audio-Video works with standard audio and video devices and with standard conferencing
applications such as Skype, WebEx, and Google Hangouts. To support Real-Time Audio-Video, your
Horizon environment must meet certain software and hardware requirements.
Remote desktops and
applications
To use Real-Time Audio-Video with published desktops and remote
applications, you must have Horizon Agent 7.0.2 or later.
Client access device Real-Time Audio Video is supported on all Chromebooks that run
Horizon Client for Chrome OS.
Preparing Connection Server for Horizon Client
A Horizon administrator must perform specic tasks to enable end users to connect to remote desktops and
applications.
Before end users can connect to a Connection Server instance or a security server and access a remote
desktop or application, a Horizon administrator must congure certain pool seings and security seings:
nIf you plan to use Unied Access Gateway, congure Connection Server to work with
Unied Access Gateway. See the Deploying and Conguring Unied Access Gateway document.
Unied Access Gateway appliances fulll the same role that was previously played by only security
servers.
nIf you are using a security server, verify that you are using the latest maintenance releases of
Connection Server 6.x and Security Server 6.x or later releases. For more information, see the View
Installation document.
nIf you plan to use a secure tunnel connection for client devices and if the secure connection is
congured with a DNS host name for Connection Server or a security server, verify that the client
device can resolve this DNS name.
To enable or disable the secure tunnel, in Horizon Administrator, go to the Edit Horizon Connection
Server Seings dialog box and use the check box called Use secure tunnel connection to desktop.
nVerify that a desktop or application pool has been created and that the user account that you plan to use
is entitled to access the pool. For information, see the Seing Up Virtual Desktops in Horizon 7 or Seing
Up Published Desktops and Applications in Horizon 7 document.
nTo use two-factor authentication with Horizon Client, such as RSA SecurID or RADIUS authentication,
you must enable this feature on Connection Server. For more information, see the topics about two-
factor authentication in the View Administration document.
nTo hide security information in Horizon Client, including server URL information and the Domain
drop-down menu, enable the Hide server information in client user interface and Hide domain list in
client user interface seings in Horizon Administrator. These global seings are available in Horizon 7
version 7.1 and later. For information about conguring global seings, see the View Administration
document.
VMware Horizon Client for Chrome OS Installation and Setup Guide
8 VMware, Inc.
To authenticate when the Domain drop-down menu is hidden, users must provide domain information
by entering their user name in the format domain\username or username@domain in the User name text
box.
I If you enable the Hide server information in client user interface and Hide domain list
in client user interface seings and select two-factor authentication (RSA SecureID or RADIUS) for the
Connection Server instance, do not enforce Windows user name matching. Enforcing Windows user
name matching will prevent users from being able to enter domain information in the user name text
box and login will always fail. For more information, see the topics about two-factor authentication in
the View Administration document.
nTo provide end users unauthenticated access to published applications in Horizon Client, you must
enable this feature in Connection Server. For more information, see the topics about unauthenticated
access in the View Administration document.
Using Embedded RSA SecurID Software Tokens
If you create and distribute RSA SecurID software tokens to end users, they need enter only their PIN, rather
than their PIN and a token code, to authenticate.
Setup Requirements
You can use Compressed Token Format (CTF) or dynamic seed provisioning, which is also called CT-KIP
(Cryptographic Token Key Initialization Protocol), to set up an easy-to-use RSA authentication system. With
this system, you generate a URL to send to end users. To install the token, end users paste this URL directly
into Horizon Client on their client devices. The dialog box for pasting this URL appears when end users
connect to a Connection Server instance with Horizon Client.
After the software token is installed, end users enter a PIN to authenticate. With external RSA tokens, end
users must enter a PIN and the token code generated by a hardware or software authentication token.
The following URL prexes are supported for end users that copy and paste the URL into Horizon Client
when Horizon Client is connected to an RSA-enabled Connection Server instance:
nviewclient-securid://
nhttp://127.0.0.1/securid/
End users can install the token by tapping the URL. Both the viewclient-securid:// and
http://127.0.0.1/securid/ prexes are supported. Not all browsers support hyperlinks that begin with
http://127.0.0.1. Some le browsers, such as the File Manager app on the ASUS Transformer Pad, cannot
link the SDTID le with Horizon Client.
For information about using dynamic seed provisioning or le-based (CTF) provisioning, see the Web page
RSA SecurID Software Token for iPhone Devices at hp://www.rsa.com/node.aspx?id=3652 or RSA SecurID
Software Token for Android at hp://www.rsa.com/node.aspx?id=3832.
Instructions to End Users
When you create a CTFString URL or CT-KIP URL to send to end users, you can generate a URL with or
without a password or activation code. You send this URL to end users in an email that must include the
following information:
nInstructions for navigating to the Install Software Token dialog box.
Tell end users to tap External Token in the Horizon Client dialog box that prompts them for RSA
SecurID credentials when they connect to a Connection Server instance.
Chapter 1 Setup and Installation
VMware, Inc. 9
nCTFString URL or CT-KIP URL in plain text.
If the URL has formaing on it, end users will get an error message when they try to use it in
Horizon Client.
nActivation code, if the CT-KIP URL that you create does not already include the activation code.
End users must enter this activation code in a text eld of the dialog box.
nIf the CT-KIP URL includes an activation code, tell end users that they need not enter anything in the
Password or Activation Code text box in the Install Software Token dialog box.
Configure Advanced TLS/SSL Options
You can select the security protocols and cryptographic algorithms that are used to encrypt communications
between Horizon Client and Horizon servers and between Horizon Client and the agent in the remote
desktop.
By default, TLSv1.0, TLSv1.1, and TLSv1.2 are enabled. SSL v2.0 and 3.0 are not supported. The default
cipher control string is "!aNULL:kECDH+AESGCM:ECDH+AESGCM:RSA+AESGCM:kECDH+AES:ECDH
+AES:RSA+AES".
If you congure a security protocol for Horizon Client that is not enabled on the Horizon server to which the
client connects, a TLS/SSL error occurs and the connection fails.
For information about conguring the security protocols that are accepted by Connection Server instances,
see the View Security document.
Procedure
1 Tap the  (gear) icon in the upper-right corner of the Horizon Client window and tap Security
options.
2 Tap Advanced SSL Options.
3 Make sure that Use Default  is unchecked.
4 To enable or disable a security protocol, tap the check box next to the security protocol name.
5 To change the cipher control string, replace the default string.
6 (Optional) If you need to revert to the default seings, tap to select the Use Default  option.
7 Tap OK to save your changes.
Your changes take eect the next time you connect to the server.
Supported Desktop Operating Systems
A Horizon administrator creates virtual machines that have a guest operating system and installs agent
software in the guest operating system. End users can log in to these virtual machines from a client device.
For a list of the supported Windows guest operating systems, see the View Installation document.

default server.
Requirements and Prerequisites
The default Connection Server URL feature has the following requirements and prerequisites.
nThe feature is supported only on Chromebooks that are enrolled and managed by G Suite
administration.
nA Chrome administrator must install the Horizon Client for Chrome OS app and the VMware Horizon
Client Helper extension through Chrome device management. Both the app and the extension are
available in the Chrome Web Store.
When a default Connection Server URL is set, the Horizon Client  (gear icon) is not visible before a
user logs in to a remote session and certain seings, such as VMware Blast and Unauthenticated access,
cannot be changed.

Horizon Client Data Collected by VMware
If your company participates in the customer experience improvement program, VMware collects data from
certain Horizon Client elds. Fields that contain sensitive information are anonymous.
VMware collects data on client systems to prioritize hardware and software compatibility. If your company's
administrator has opted to participate in the customer experience improvement program, VMware collects
anonymous data about your deployment to respond beer to customer requirements. VMware does not
collect data that identies your organization. Horizon Client information is sent rst to the Connection
Server instance and then to VMware, with data from Connection Server, desktop pools, and remote
desktops.
The administrator who installs Connection Server can select whether to participate in the VMware customer
experience improvement program while running the Connection Server installation wizard, or an
administrator can set an option in Horizon Administrator after the installation.

Managing Remote Desktop and
Application Connections 2
End users can use Horizon Client to connect to a server, edit the list of servers they connect to, log in to or
o of remote desktops, and use remote applications. For troubleshooting purposes, end users can also reset
remote desktops and applications.
Depending on how you congure policies for remote desktops, end users might be able to perform many
operations on their desktops.
This chapter includes the following topics:
n“Seing the Certicate Checking Mode in Horizon Client,” on page 17
n“Connect to a Remote Desktop or Application,” on page 18
n“Use Unauthenticated Access to Connect to Remote Applications,” on page 20
n“Manage Server Shortcuts,” on page 21

n“Log O From a Remote Desktop,” on page 22
n“Manage Desktop and Application Shortcuts,” on page 23
Setting the Certificate Checking Mode in Horizon Client
You can determine whether client connections are rejected if any or some server certicate checks fail by
conguring a seing in Horizon Client.
Certicate checking occurs for SSL connections between the server and Horizon Client. Certicate
verication includes the following checks:
nIs the certicate intended for a purpose other than verifying the identity of the sender and encrypting
server communications? That is, is it the correct type of certicate?
nHas the certicate expired, or is it valid only in the future? That is, is the certicate valid according to
the computer clock?
nDoes the common name on the certicate match the host name of the server that sends it? A mismatch
can occur if a load balancer redirects Horizon Client to a server that has a certicate that does not match
the host name entered in Horizon Client. Another reason a mismatch can occur is if you enter an IP
address rather than a host name in the client.
VMware, Inc. 17
nIs the certicate signed by an unknown or untrusted certicate authority (CA)? Self-signed certicates
are one type of untrusted CA.
To pass this check, the certicate's chain of trust must be rooted in the device's local certicate store.
N For information about distributing a self-signed root certicate that users can install on their Chrome
OS devices, as well as instructions for installing a certicate on a Chrome OS device, see the documentation
on the Google Web site.
To set the certicate checking mode, start Horizon Client and tap the  (gear) icon in the upper-right
corner of the Horizon Client window, tap Security options, and tap Security mode. You have three choices:
nNever connect to untrusted servers. If any of the certicate checks fails, the client cannot connect to the
server. An error message lists the checks that failed.
nWarn before connecting to untrusted servers. If a certicate check fails because the server uses a self-
signed certicate, you can click Continue to ignore the warning. For self-signed certicates, the
certicate name is not required to match the server name you entered in Horizon Client.
nDo not verify server identity . This seing means that no certicate checking occurs.
If the certicate checking mode is set to Warn, you can still connect to a server that uses a self-signed
certicate.
If an administrator later installs a security certicate from a trusted certicate authority, so that all certicate
checks pass when you connect, this trusted connection is remembered for that specic server. In the future,
if that server ever presents a self-signed certicate again, the connection fails. After a particular server
presents a fully veriable certicate, it must always do so.
Connect to a Remote Desktop or Application
To connect to a remote desktop or application, you must provide the name of a server and supply
credentials for your user account.
Before you have end users access their remote desktops and applications, test that you can connect to a
remote desktop or application from a client device. You might need to specify a server and supply
credentials for your user account.
Prerequisites
nObtain login credentials, such as an Active Directory user name and password, RSA SecurID user name
and passcode, or RADIUS authentication user name and passcode.
nPerform the administrative tasks described in “Preparing Connection Server for Horizon Client,” on
page 8.
nIf you are outside the corporate network and require a VPN connection to access remote desktops and
applications, verify that the client device is set up to use a VPN connection and turn on that connection.
nVerify that you have the fully qualied domain name (FQDN) of the server that provides access to the
remote desktop or application. Underscores (_) are not supported in server names. If the port is not 443,
you also need the port number.
nIf you plan to use embedded RSA SecurID software, verify that you have the correct CT-KIP URL and
activation code. See “Using Embedded RSA SecurID Software Tokens,” on page 9.
nCongure the certicate checking mode for the SSL certicate presented by the server. See “Seing the
Certicate Checking Mode in Horizon Client,” on page 17.
Procedure
1 If a VPN connection is required, turn on the VPN.
VMware Horizon Client for Chrome OS Installation and Setup Guide
18 VMware, Inc.
2 On the Chrome OS device, tap the Chrome App Launcher icon in the taskbar and tap the Horizon
Client for Chrome OS app.
The Horizon Client window opens.
3 Connect to a server.
Option Action
Connect to a new server Enter the name of a server, enter a description (optional), and tap Connect.
Connect to a existing server Tap the server shortcut on the Servers tab.
Connections between Horizon Client and servers always use SSL. The default port for SSL connections
is 443. If the sever is not congured to use the default port, use the format shown in this example:
view.company.com:1443.
4 If you are prompted for RSA SecurID credentials or RADIUS authentication credentials, either type
your credentials or, if you plan to use an embedded RSA SecurID token, install an embedded token.
Option Action
Existing token If you use a hardware authentication token or software authentication
token on a smart phone, enter your user name and passcode. The passcode
might include both a PIN and the generated number on the token.
Install software token Tap External Token. In the Install Software Token dialog box, paste the CT-
KIP URL or CTFString URL that your administrator sent to you in email. If
the URL contains an activation code, you do not need to enter anything in
the Password or Activation Code text box.
5 If you are prompted a second time for RSA SecurID credentials or RADIUS authentication credentials,
enter the next generated number on the token.
Do not enter your PIN and do not enter the same generated number entered previously. If necessary,
wait until a new number is generated.
If this step is required, it is required only when you mistype the rst passcode or when conguration
seings in the RSA server change.
6 In the login dialog box, type your user name and password, select a domain, and tap Connect.
If the Domain drop-down menu is hidden, you must type the user name as username@domain or
domain\username.
7 (Optional) Tap the display protocol seings icon in the upper-right corner of the screen to select the
display protocol to use.
VMware Blast provides beer baery life and is the best protocol for high-end 3D and mobile device
users. The default display protocol is PCoIP.
8 Tap a remote desktop or application icon to connect to it.
After you connect to a remote desktop or application for the rst time, a shortcut for the desktop or
application is saved to the Recent tab. The next time you want to connect to the remote desktop or
application, you can tap this shortcut.
If Horizon Client cannot connect to the remote desktop, perform the following tasks:
nDetermine whether Connection Server is congured not to use SSL. Horizon Client requires SSL
connections. Check whether the global seing in Horizon Administrator for the Use SSL for client
connections check box is deselected. If so, you must either select the check box, so that SSL is used, or
set up your environment so that clients can connect to an HTTPS enabled load balancer or other

Use Unauthenticated Access to Connect to Remote Applications
A Horizon administrator can use the Unauthenticated Access feature to create Unauthenticated Access users
and entitle those users to remote applications on a Connection Server instance. Unauthenticated Access
users can log in to the server anonymously to connect to their remote applications.
Before you have end users access a remote application with the Unauthenticated User feature, test that you
can connect to the remote application from a client device. You might need to specify a server and supply
credentials for your user account.
Prerequisites
nPerform the administrative tasks described in “Preparing Connection Server for Horizon Client,” on
page 8.
nSet up Unauthenticated Access users on the Connection Server instance. For information, see
"Providing Unauthenticated Access for Published Applications" in the View Administration document.

When the window freezes, rst, try reseing the remote desktop operating system.
Problem
Horizon Client does not work or repeatedly exits unexpectedly or the remote desktop freezes.
Cause
Assuming that Horizon servers are congured properly and that rewalls surrounding them have the
correct ports open, other issues usually relate to Horizon Client on the device or to the guest operating
system on the remote desktop.
Solution
nIf the operating system in the remote desktop freezes, use Horizon Client on the device to reset the
desktop.
This option is available only if the Horizon administrator has enabled this feature.
nUninstall and reinstall the app on the device.
nIf reseing the remote desktop and reinstalling Horizon Client do not help, you can reset the Chrome
OS device, as described in the device user guide.
nIf you get a connection error when you aempt to connect to the server, you might need to change your
proxy seings.
Problem Establishing a Connection When Using a Proxy
Sometimes if you aempt to connect to Connection Server using a proxy while on the LAN, an error occurs.
Problem
If the Horizon environment is set up to use a secure connection from the remote desktop to Connection
Server, and if the client device is congured to use an HTTP proxy, you might not be able to connect.
Cause
Unlike Windows Internet Explorer, the client device does not have an Internet option to bypass the proxy
for local addresses. When an HTTP proxy is used for browsing external addresses, and you try to connect to
Connection Server using an internal address, you might see the error message Could not establish
connection.
Solution
uRemove the proxy seings so that the device no longer uses a proxy.
