MinimWatch fails on Windows 10 Pro

[simbun]

I am running 64-bit java, it stated that in the minimwatch.log too

Code:

MinimWatch 0.8.5.3 update 64, Copyright (c) 2012-2019 Simon Nash. All rights reserved.
Java(TM) SE Runtime Environment (build 1.8.0_241-b07)
Java HotSpot(TM) 64-Bit Server VM (build 25.241-b07, mixed mode)
Platform default charset is windows-1252
Active subnet is 192.168.20.0

It also stated 64-bit on std out from calling startc.cmd

Code:

Java VM: Java HotSpot(TM) 64-Bit Server VM (25.241-b07 mixed mode windows-amd64 compressed oops)

Just to be absolutely sure I've uninstalled Java and reinstalled 64-bit Java with the same outcome.

I don't have any minimwatch-crash- files.

Don't MinimServer and MinimWatch have the same requirements (of Java at least)?
