User-added image

The installation was not "Run as an Administrator".

Or there was a firewall preventing contact with the machine running SQL.

Resolution

UPDATED: November 1, 2017
Re-run the content author configuration manager from the icon on the desktop (right click and run as administrator). Once the setup tool opens, run all the steps again.

Also ensure that the machine running SQL has no firewall enabled and SQL server is running in mixed mode. 

Once all done, try using Content Author again.
