Windows Media Format Runtime is required on servers where you install Conferencing Attendant or Conferencing Announcement Service. If you use SetupEE.exe or SetupSE.exe to install Office Communications Server 2007 R2, it prompts you and then automatically installs Windows Media Format Runtime if it is not already on the computer. You need to manually install the Windows Media Format Runtime only if you use the command line to install Office Communications Server 2007 R2. Installing this component might require a system restart.
Conferencing Attendant and Conferencing Announcement Service use the Windows Media audio (WMA) file format to play prompts, music, and announcements. The WMA file format requires the Windows Media Format Runtime to run properly.
