I'm currently at version 12.0.6118.4 on my SQL Server 2014 SP3 and when I attempt to install CU4 I get this message:
A SQL Server update with a higher version has already been installed on SQL Server instance MSSQLSERVER, so the current SQL Server update cannot be applied. The version of the SQL Server update that is already installed is GDR 12.3.6118.4(12.3.6370.0) with a KBKB4532095 and the current SQL Server update is 12.3.6329.1 with a KBKB4500181.
How do I resolve this, so that I can bring my server up to the latest CU update?
