Cannot build lighting

I have a VR scene to light in 4.14.3, when I run a light build Swarm will show in the taskbar, but it never starts the process. In the editor I do not get a lighting building status.
I also have vers 4.0.2 installed, I was able to build lighting in the template maps in the older version, but when I opened the same scene in 4.14.3 it would not build.

There are a few logs that are showing in red in the output log, I can paste the rest in but this look like a problem. It cannot connect to a host, but its set to stand alone mode:

LogSwarmInterface:Error: [TryOpenConnection] Waiting for the agent to start up …
LogSwarmInterface:Error: System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it 127.0.0.1:8008
Server stack trace:

Actually that was not the issue. I had to put RENDER-01 back in as the host. I had removed it before when setting it to stand alone mode. Now I get no error messages, but the same issue - not lighting gets built.

I solved this with a reformat of my drives, re-install Windows, service packs, .net framework, and UE4.
