You actually have the answer for your question in your first screen. windows tells you that this program is designed to be the Service and could not run from the command line. It also suggests that you use insyalutil to set your program as a service and then Windows will run it when it will need it. Ususally service runs for some events. Most common - user connects to particular port associated with this service (for example port 80) and when such request occurs then Windows starts service progarm (IIS to answer http call) and delegate this request to this new program. Or delegeates it immediately if program is already running.

So, as you can see, Windows is in charge of the service programs. You cannot start them from command line of from another process (that's your example). You can start/stop/restart process manually in the service control window but that's still not command line or your process.
