To support Windows Media Multimedia Redirection (MMR), your View deployment must meet certain software and hardware requirements. Windows Media MMR is provided in Horizon 6.0.2 and later releases.

Horizon 6.0.1 and earlier releases provide the Win7 MMR component for Windows 7 desktops and clients.

For a comparison of the Windows Media MMR, Win7 MMR, and Wyse MMR components, see Multimedia Redirection Support on Desktop Operating Systems.

View desktop

  • The desktops must run one of the following operating systems:

    • 64-bit or 32-bit Windows 7 Enterprise or Ultimate

    • 64-bit or 32-bit Windows 8/8.1 Professional or Enterprise

  • 3D Rendering can be enabled or disabled on the desktop pool.

  • Users must play videos on Windows Media Player 12 or later or in Internet Explorer 8 or later.

    To use Internet Explorer, you must disable Protected Mode. In the Internet Options dialog box, click the Security tab and deselect Enable Protected Mode.

View policies

In View Administrator, set the Multimedia redirection (MMR) policy to Allow. The default value is Deny.
