minimwatch unable to detect minimserver

[trevorausten]

I have been running MinimServer/Streamer on my desktop (Windows 10) without problems. I have just bought a Melco NZH and successfully installed MinimServer on it. I am able to see MinimServer on the Melco as a networked device from the desktop. The Melco is directly connected to the DAC. Bubble DSNext sees the Melco/DAC as renderer and MinimServer as Library and I am able to play the library.
I cannot install MinimWatch.
I exit the desktop MinimWatch and download and run MinimWatch installer to try to pick up the Melco Minimwatch. A grey icon appears in the tray. The log is:
MinimWatch 0.8.4 update 49, Copyright © 2012-2017 Simon Nash. All rights reserved.
Java™ SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot™ 64-Bit Server VM (build 25.121-b13, mixed mode)
Platform default charset is windows-1252
Active subnet is 192.168.56.0
Startup complete
The IP address of the Melco is 192.168.1.108, subnet mask 255.255.255.0
I do not recognise 192.168.56.0
I have turned off the firewall and "Java ™ Platform SE binary" is enabled in all cases (private network).
What am I doing wrong?
