Hi

pls try this

-

once you have written your service U need to add an installer class;
System.Configuration.Install.Installer.
In the constructor, you need to add a System.ServiceProcess.ServiceProcessInstaller to your Installers collection. This will install the process where your service resides. Set its Username and Password properties to match the username and password of the account you'd like the process to run

try the code below

using System
using System.Configuration.Install
using System.ServiceProcess
using System.ComponentModel

public class MyInstaller : Installe

 public MyInstaller(
 
   ServiceProcessInstaller servprocinstl = new ServiceProcessInstaller()
   servprocinstl.Username = "yourDOMAIN\\yourusername"
   servprocinstl.Password = "yourpassword"

   ServiceInstaller servinstl = new ServiceInstaller()
   servinstl.ServiceName = "name of the service"

   this.Installers.Add(servprocinstl)
   this.Installers.Add(servinstl)
 

hope this works :

Regards
