Update BIDS 2008 R2 to SP1

I have Windows 2008 R2 server.

BIDS is the only SQL Server component installed on this box (2008 R2 RTM).

When I was trying to upgrade BIDS to SP1, I got following error:

This version of SQL Server instance Share components does not match the version expected by the SQL Server update. Installed version is 10.50.1447.4 and the expected SQL Server version is 10.50.1600.1.
