Installation of SQL Server 2014 fails on Windows Server 2012 R2 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":

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.

Uninstalling SqlSupport.msi allowed the installation to proceed correctly.
