I am attempting to run a silent installation of SQL Server 2014 with SP1 on Windows Server 2012 R2 core install, although it also fails when using UIMODE="EnableUIOnServerCore":

(01) 2016-02-05 19:48:33 Slp: Running Action: ExpandInstallFeatures
(01) 2016-02-05 19:48:33 Slp: Error: Action > "Microsoft.SqlServer.Configuration.SetupExtension.ExpandInstallFeatures" threw an exception during execution.
(01) 2016-02-05 19:48:33 Slp: Microsoft.SqlServer.Setup.Chainer.Workflow.ActionExecutionException: Unable to load DLL 'sqlconf.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E) ---> System.DllNotFoundException: Unable to load DLL 'sqlconf.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Error result: -2146233052
Result facility code: 19
Result error code: 5412

Any thoughts on why sqlconf.dll would not be present? Prior to the installation I have run SqlSupport.msi.

This server is part of a two-node FCI which is meant for AlwaysOn.

    The log you posted are not enough to help you out. Use this link to add output of summary.txt in the question. Have you read Install SQL Server 2014 on Server Core – Shanky Feb 6 '16 at 16:48
  • There's not much else in the log, but a link is available. – Trevor Seward Feb 6 '16 at 16:59
  • It seems to me the error is because .Net Framework is not installed or missing. Have you enabled .NET Framework 3.5 SP1 Full Profile and NET Framework 4 Server Core Profile. Please read the link I shared in my first reply – Shanky Feb 6 '16 at 17:16
  • Yes, both are installed. – Trevor Seward Feb 6 '16 at 17:17
  • Do you actually reach to installation or the exception is coming while selecting options. If so where you are getting the exception – Shanky Feb 6 '16 at 17:20

Uninstalling SqlSupport.msi allowed the installation to proceed correctly.

A reinstallation of the Visual C++ Redistributable 2010 worked for me. (https://support.microsoft.com/en-us/kb/2977003)

The bit width should be the same as that of the installed MS SQL Server.
