Cumulative update 15 for SQL Server 2012 SP2

Cumulative Update 15 (CU15) for Microsoft SQL Server 2012 Service Pack 2 (SP2) was also released as a SQL Server Security Bulletin on 11/8/2016, KB3194725. See MS16-136 for more information. Because of this, you may already have CU15 installed as part of that security bulletin release and installation of this CU is unnecessary. If you do try to install CU15 after MS16-136, you may receive the following message:

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

Note This message indicates that CU15 is already installed and no further action is required.

Note The package name for CU15, "SQLServer2012-KB3194725-<x86/x64>.exe", contains the MS16-136 KB number (3194725), not the CU15 KB number, (3205416). This can be ignored as a single package services both release channels.

This article describes cumulative update package 15 (build number: 11.0.5676.0) for SQL Server 2012 SP2. This update contains fixes that were released after the release of SQL Server 2012 SP2.
