I am getting this message and have SP1 installed. Here is the results of SELECT @@version from my MSSMS:
(No column name)
Microsoft SQL Server 2012 - 11.0.5343.0 (X64)
May 4 2015 19:11:32
Copyright (c) Microsoft Corporation
Developer Edition (64-bit) on Windows NT 6.1 <X64> (Build 7601: Service Pack 1)
The version is higher than SP1, however the last line displays Service Pack 1. Any ideas on why it won't install SP2?
Many thanks,
Keith
