SQL Server 2016 SP1 CU1 Install Fails
The installer that I was initially using was SQL Server 2016 Developer with SP1. When I would try and apply CU1 for SP1 it was failing. I downloaded the SQL Server 2016 Developer RTM and installed it. I then applied SP1, rebooted and applied CU1 for SP1 and that worked. What I am not sure of is why there is a difference between the two scenarios.
