Hi, I just updated my 2012 SQL server to SP2 and got the same issue.
Microsoft SQL Server 2012 (SP2-GDR) (KB3194719) - 11.0.5388.0 (X64) Sep 23 2016 16:56:29 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 6.3 <X64> (Build 9600: ) (Hypervisor)
I am using Telerik OpenAccess 2014.3.1209.1
I override the file in the my projects bin folder with the hotfix above but got the below error.
Exception message: Could not load file or assembly 'Telerik.OpenAccess.Runtime, Version=2014.3.1209.1, Culture=neutral, PublicKeyToken=7ce17eeaf1d59342' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) (\\KICSFILES\KICSWebsites\staging.kics.com.au\web.config line 107)
I'm installing SP3 on the server now to see if it resolves it.
