Installer - Zope as a Windows Service?


i hope you can help me. I use Plone with Python 2.7 under Windows server 2012.
When i start plonectl fg it´s work but i don´t close the CMD Windows.

When i start plonectl start i get the Error:

C:\Users\Administrator.ORD\Plone\zinstance\bin>plonectl start
instance: ERROR: Zope is not installed as Windows service.

Why can i install the Service.



My windows is a bit rusty. AFAIK there was a bin/instance install or bin/instance install auto (for auto-start of the service on system start-up) command to get it installed as windows service. Maybe using the unified-installer it is plonectl install ... then?
