ASCOM Platform is the standard astronomical equipment driver for Windows.
Install the latest ASCOM platform and the drivers you need from http://ascom-standards.org/Downloads/Index.htm or from your equipment manufacturer.
To use the ASCOM driver remotely, from another Windows computer, or from a computer running Linux or macOS you must install the ASCOM REST Server.
A very important point when using Windows astronomy software is to
NEVER run anything as administrator
this is the source of many issue when accessing shared resources like a ASCOM driver. No current software need that despite the popularity of this false advice in astronomy forum.
