Tried installing officeserver2010sp1-kb2460045-x64-fullfile-en-us, "The expected version of this product was not found on this system."

I'm having problems installing SP1 on my Win2008 SP2 SharePoint Server 2010 Standard CA machine.

Configuration database version: 14.0.6029.1000

Anyone familiar with this issue? Any prerequisites necessary? 

I checked the 'Top Related Threads' but they were for MOSS 2007.

Thanks.
