NOTE:This is not an exhaustive list of formats that are affected by this issue. Other file types and formats may also encounter this issue.
The only known workaround is to uninstall Silverlight 5 runtime from the client PC and re-install the Silverlight 4 runtime.
NOTE: If this option is chosen and Microsoft Update is enabled Windows Update will identify an available Important update for Silverlight any time a scan for available updates is run. It will be necessary to unselect the Important update for Silverlight to prevent Windows Update from upgrading the Silverlight 4 runtime to the latest release of the Silverlight 5 runtime.
