Cannot install or un-install Minimserver

[Arbie19]

Today I discovered Minimserver had disappeared from the network. I have it running on a 64 bit Windows 7 PC.

Checking the PC, there is no icon for Minimserver. I attempted to re-install, but was informed that Minimserver was already running and that I would have to stop it to re-install. Checking installed programs within Control Panel, Minismserver 0.8.4 is shown as installed. However Task Manager, the web page n.n.n.n:9790 and minimwatch all show the server is not running. I have tried safe mode to un-install with the same result. Also Minimserver is switched off in start-up under System Configuration.

Very baffling. Any thoughts?
