How to auto-start my own .NET app when Windows starts?

Thanks for your help everyone.
I have not figured it out but made a workaround. I wrote a tiny app that starts the manager. This app auto-starts fine and then the main app also runs. Not ideal but it works...

Code:

using System;
using System.Linq;
using System.Text;

namespace ManagerStarter
{
    class Program
    {
        static void Main(string[] args)
        {
            if (args.Count() > 0)
            {
                System.Diagnostics.Process.Start(args[0]);
            }
            else
            {
                Console.WriteLine("Error: No executable specified.");
                Console.WriteLine("Usage: ManagerStarter <executable file to start>");
                Console.WriteLine("Press any key to exit.");
                Console.ReadKey();
            }
        }
    }
}
