starting up for dummies

[rhkrhk]

Using windows 7, 64 bit, with Java v8 update 91, I downloaded minimserver.
I click on the desktop icon, but nothing happens. Task manager shows "new thread in general- mozilla firefox", no entries for minim in task mgr/processes.

Somehow, the computer thinks minimserver is open because when I try to uninstall it is "Minimserver is running..." pops up.

Current setup uses JRiver Media Center v23 as default music player. What is lacking is ability to use streaming internet radio via my router to PSAudio Direct Stream Bridge I.

Website Instructions are not very helpful. Can anyone point me to a simple and comprehensible set of instructions?
thanks
