How to get ORM support in Visio 2010?

Hi all,

I have recently bought a new computer, and upgraded almost my entire
software suite. One of many replacements is that I moved from Office
2003 to Office 2010. This includes the move from Visio 2003 for
Enterprise Architects to Visio 2010 - I did not find an Enterprise
Architects edition, so I chose the Premium edition, figuring that this
should include all options.

When I just tried to open an existing diagram, it opened all right,
but with a warning message: "No support for the ORM source model has
been installed" (not a direct quote; I translated from Dutch to
English).

Is support for ORM source model diagrams a seperate download? If so,
where do I find it?
