 You will be prompted to enter the full path to the application you wish

 Use the system service manager (services.msc) to control advanced service

 support these options at a later time...
 
 
+Installation using the command line
+-----------------------------------
+To install a service, run

+
+NSSM will then attempt to install a service which runs the named application
