What is the standard way of creating an online installer?

Question

What I mean is something like the installers for Visual Studio, where the installer is a very small application, which in turn downloads the actual application. What I'm trying to achieve is to have more control over installations - If we release a new version - we want all installations to be of the new version (as opposed to a regular installer which will install the same version no matter when it's used).

I know of Clickonce but that installs a program for one user only.

Is there some standard way of doing it? Is there some template for it? I'm not looking for any 3rd party software. I'm looking for a standard way of coding this or something in Visual Studio / any other Microsoft technology.

This isn't tested, but could you call msiexec? It takes a remote URL as a valid location for your msi file. I found a couple articles that may be helpful regarding this:

This answer has the C# code to do it using the windows installer COM object: Programatically installing MSI packages

Answer snippet from the question: using System; using WindowsInstaller;

namespace TestApp
{
    public class InstallerTest
    {
        public static void Install()
        {
            Type type = Type.GetTypeFromProgID("WindowsInstaller.Installer");
            Installer installer = (Installer)Activator.CreateInstance(type);
            installer.InstallProduct("YourPackage.msi");
        }
    }
}

If you need to add switches to the installer or deploy a .msp upgrade when you update your version, here is the full blown model:
