I created a VM using the standard Azure image "SQL Server 2014 SP1 Express on Windows Server 2012 R2".
I immediately ran Windows Update and all patches for the server worked but the Security Update for SQL Server 2014 Service Pack 1 (KB3070446) failed. Error code: 84B30002
The Azure VM SQL Express version (SELECT @@VERSION) is: "Microsoft SQL Server 2014 - 12.0.4193.9 (X64) Nov 28 2015 03:44:12 Copyright (c) Microsoft Corporation Express Edition (64-bit) on Windows NT 6.3 (Build 9600: ) (Hypervisor)".
This version is not a documented SQL Express 2014 version (as far as I can see here).
I have tried installing CU 5 for SQL Express 2014 but that couldn't find a valid version of SQL Server to update.
Do you think it is non-standard version that is causing the update to fail? I am stuck.
