You can allow only one user run your program by using a hardware ID to identify the user using the application or you can use a licensing system.

run the code below on the machine that you want your .exe. file to work on (it will give you this machines MAC address). 2. Add this MAC address to the code below 3. Add the code below to your C# code to ensure that it only runs on the machine with the correct MAC address (unique)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.NetworkInformation;
using System.Text;
using System.Threading.Tasks;

namespace OneMachine
{
    class Program
    {
        static void Main(string[] args)
        {

            string clientMAC = "XX-XX-XX-XX-XX-XX";       //  put the correct value here when you know it
            string thisComputerMAC = GetMACAddress2();

            Console.WriteLine("MAC:" + thisComputerMAC);   // remove this when necessary

            if (clientMAC == thisComputerMAC)
            {

                Console.WriteLine("this is the right computer");
            } else
            {
                Console.WriteLine("PROGRAM WONT RUN ON THIS COMPUTER");
            }


        }

        public static string GetMACAddress2()
        {
            NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
            String sMacAddress = string.Empty;
            foreach (NetworkInterface adapter in nics)
            {
                if (sMacAddress == String.Empty)// only return MAC Address from first card  
                {
                    //IPInterfaceProperties properties = adapter.GetIPProperties(); Line is not required
                    sMacAddress = adapter.GetPhysicalAddress().ToString();
                }
            } return sMacAddress;
        }


    }
}

u can create the security constrain for exe like

  1. by Giving unique password
  2. By Entering the serial Key i.e. Licence Key which will know to u only or create random serial key generator based on the system.

I think what you want would be some sort of licence key and an authorization method.

A quick google turned up this article which you may find useful.
