I have just upgraded to 5.1.2.0 (on Win10 Creators Update)

The upgrade process stopped the server process but didn't restart it afterwards. The services-entry said 'Automatic' but the server remained stopped. Mezzmos console also said 'Start Server' - means recognized the server as stopped. I started the process via the Mezzmo console without any error messages and it seems to run fine.

Other than that everything I am using Mezzmo for (HD video and flac streaming) seems to run fine. Job well done Conceiva!

Cheers
Bernhard
