SQL Server Instance Version I'm working with a SQL Server with several instances. Four of my instances are at 10.50.2811.0 and the remaining two are at 10.50.1765.0

I've tried running SQL Server 2008 R2 SP1 and CU 6 to get it updated but the installer wont run. I receive the error:


  To continue, select a feature to install. If all features are already selected, these features are installed.
Basically, you have to install SP1 and then CU6 (as mentioned in my comment)


10.50.2811 ==> 2679367 Cumulative update package 6 (CU6) for SQL Server 2008 R2 Service Pack 1 
10.50.1765 ==> 2489376 Cumulative update package 6 (CU6) for SQL Server 2008 R2 note this is for RTM
