Question

I am using InstallUtil to install my service and I just cannot figure out how to specify the startup parameters for it!

Here is my Installer subclass:

I know this is an old post but thought I'd post my response. I did this in a .net 4 service using the BeforeInstall event.

The ServiceProcessInstaller's BeforeInstall event:

private void serviceProcessInstaller1_BeforeInstall(object sender, InstallEventArgs e)
{
    System.ServiceProcess.ServiceProcessInstaller installer = sender as System.ServiceProcess.ServiceProcessInstaller;

    if (installer != null)
    {
        //Get the existing assembly path parameter
        StringBuilder sbPathWIthParams = new StringBuilder(installer.Context.Parameters["assemblypath"]);

        //Wrap the existing path in quotes if it isn't already
        if (!sbPathWIthParams[0].Equals("\""))
        {
            sbPathWIthParams.Insert(0, "\"");
            sbPathWIthParams.Append("\"");
        }

        //Add desired parameters
        sbPathWIthParams.Append(" test");

        //Set the new path
        installer.Context.Parameters["assemblypath"] = sbPathWIthParams.ToString();
    }
}

The installed service looks as follows:

It executes fine, and I can examine the parameters from within the main function of the service.
