Symptoms

When doing a clean install of an Orchestrator 1801 management server, my install failed with “DBSetup.exe failed with unknown error 0x800A0E7A”. I checked the DBSetup log, located at C:\ProgramData\Microsoft System Center 2012\Orchestrator\DBSetup.exe\Logs, and saw this error:

Cause

Since 1801 encompasses all the update rollups from 2016, it also has update rollup 4 included. One of the requirements of UR4 is the Microsoft SQL Server 2012 Native Client – QFE. Thus, this is also a prerequisite of 1801. This prerequisite is not verified by the 1801 installer and needs to be installed on the proposed management server beforehand.

Resolution

Download and install the Microsoft SQL Server 2012 Native Client – QFE on the Orchestrator management server in order to clear up this error.

Download the Native Client directly here.
Or find it on Microsoft’s website, here.
