Configuring Remote Desktop Features

Table Of Contents
Prerequisites
n
Compile a white list of Web sites to ensure that only the URLs specied in the list will be able to redirect
Flash content. Although you can compile a black list of Web sites, you cannot use the Windows registry
seings to enable the black list. A black list ensures that only the URLs specied in the list will not be
able to redirect Flash content. To enable a black list, you must use the GPO seings for Flash
Redirection.
n
Verify that Horizon Agent 7.0 or later is installed in the remote desktop, along with Flash Player and
Internet Explorer 9, 10, or 11. See “Install and Congure Flash Redirection,” on page 16.
n
Verify that you are using Horizon Client 4.0 or later, along with Flash Player ActiveX version.
Procedure
1 Use Horizon Client to access the remote desktop (agent machine).
2 Open the Windows Registry Editor (regedit.exe) on the agent machine, navigate to the following
folder, and set FlashRedirection to 1:
HKLM\Software\VMware, Inc.\VMware FlashMMR
N This seing enables the Flash Redirection feature, but if this seing is disabled (set to 0) in
HKLM\Software\Policies\VMware, Inc.\VMware FlashMMR, it means Flash Redirection is disabled
domain-wide, and requires a domain administrator to enable it.
3 Navigate to the following folder:
HKEY_CURRENT_USER\SOFTWARE\VMware, Inc.\VMware FlashMMR
If this folder does not already exist, create it.
4 In the VMware FlashMMR folder, create a sub-key named UrlWhiteList.
5 Right-click the UrlWhiteList key, select New > String Value, and for the name, enter the URL of a Web
site that will use Flash Redirection.
You can use regular expressions. For example, you could specify https://*.google.com. Be sure to leave
the Data value empty.
6 (Optional) (Horizon 7.0.1 and 7.0.2 only) In the data eld of the new registry value, add the data
requireIECompatibility=true, appMode=0, or both (use a comma to separate the two strings).
Web sites support HTML5 by default and Flash Redirection does not work with these Web sites. You
must set requireIECompatibility=true for these sites to work. This parameter is not required for the
YouTube Web site.
By default, external interface support is enabled when Flash Redirection runs. This can degrade
performance. For Horizon 7.0.1 or later, in certain situations, seing appMode=0 can improve
performance, and seing appMode=1 can result in a beer user experience.
7 Repeat the previous step to add additional URLs, and when you are nished, close the Registry Editor.
8 On the agent machine, open a command prompt and change to the following directory:
%Program Files%\Common Files\VMware\Remote Experience
9 Run the following command to add the white list to Internet Explorer.
cscript mergeflashmmrwhitelist.vbs
10 Restart Internet Explorer.
The sites set with the parameter requireIECompatibility=true are added to Internet Explorer's
compatibility view. You can verify this by selecting Tools > Compatibility View  from the
menu bar.
