Install the Horizon HTML5 Redirection Extension for Google Chrome

To use the HTML5 Multimedia Redirection feature with the Google Chrome browser, you must install the Horizon HTML5 Redirection extension on the remote desktop. You can install the extension from the Chrome Web Store. Alternatively, you can install the extension silently, without user interaction, by using group policy.

To apply the Google Chrome group policy setting to the remote desktop, you must add the ADMX template file to a GPO on your Active Directory server. For a virtual desktop, the GPO must be linked to the OU that contains the virtual desktop. For a published desktop, the GPO must be linked to the OU that contains the RDS host.

Prerequisites

• Configure the HTML5 Multimedia Redirection feature. See Install and Configure HTML5 Multimedia Redirection.
• If you plan to use group policy, verify that you can log in as an Administrator domain user on the machine that hosts your Active Directory server and make sure that the MMC and the Group Policy Object Editor snap-in are available on your Active Directory server.
