applying SP1

Hi,

I am applying SP1 on SQL Server 2012 "SQLServer2012SP1_CU1-KB2765331-x64" , but it gives error

"The version of SQL Server instance Shared Component does not match the version expected by the SQL Server update. The installed SQL Server product version is 11.0.2100.60, and the expected SQL Server version is 11.1.3000.0."

"

There are no SQL Server instances or shared features that can be updated on this computer."

Please advice
