How to install the SQL 2008 R2 WMI provider

I have a C# WinForms application that queries the SQL Server WMI namespace (\Microsoft\SqlServer). With SQL Server 2005, I could install the client connectivity components to install this namespace and the WMI provide开发者_JS百科r. With SQL Server 2008 R2, this does not appear to be the case. Does anyone know which SQL component (msi package) I can run to install the SQL 2008 WMI provider without having to actually install the database itself?
