Installing SQL Server 2005 Management Studio after Jan2007 Orcas

Does anyone know how to install SQL Server Management Studio after installing Orcas? I've done my usual way of installing it after a VS2005 install, however, this time, I cannot check the checkbox that installs it (from the SQL Server 2005 install) (it says it's already installed,but actually it's because it's a different version).

So instead of trying to install that, I wanted to connect to my SQLce database, and it allows me to select the appropriate provider but when I test the connection, it says the assembly isn't installed (not verbatim).

Any thoughts?
