Inno Setup for Windows service?

I have a .Net Windows service. I want to create an installer to install that windows service.

Basically, it has to do the following:


  1. Pack
    installutil.exe
    (Is it required?)

  2. Run
    installutil.exe
    MyService.exe

  3. Start MyService



Also, I want to provide an uninstaller which runs the following command:

installutil.exe /u MyService.exe


How to do these using Inno Setup?

Answer

You don't need installutil.exe and probably you don't even have rights to redistribute it.

Here is the way I'm doing it in my application:

using System;
using System.Collections.Generic;
using System.Configuration.Install; 
using System.IO;
using System.Linq;
using System.Reflection; 
using System.ServiceProcess;
using System.Text;

static void Main(string[] args)
{
    if (System.Environment.UserInteractive)
    {
        string parameter = string.Concat(args);
        switch (parameter)
        {
            case "--install":
                ManagedInstallerClass.InstallHelper(new string[] { Assembly.GetExecutingAssembly().Location });
                break;
            case "--uninstall":
                ManagedInstallerClass.InstallHelper(new string[] { "/u", Assembly.GetExecutingAssembly().Location });
                break;
        }
    }
    else
    {
        ServiceBase.Run(new WindowsService());
    }
}

Basically you can have your service to install/uninstall on its own by using ManagedInstallerClass as shown in my example.

Then it's just matter of adding into your InnoSetup script something like this:

[Run]
Filename: "{app}\MYSERVICE.EXE"; Parameters: "--install"

[UninstallRun]
Filename: "{app}\MYSERVICE.EXE"; Parameters: "--uninstall"
