title: Automatic update solutions for a Win32 application?
body: <p>We've got a desktop product, made up of a Win32 service, a notification icon application and associated DLL files.</p>
  
  <p>I've been tasked to look at making it auto-update. We could write our own updater, but before we do that, I'd like to see what else is out there. Are there any commercial systems (similar to Windows Update, I guess) that we could use? I'm sure that InstallShield used to offer something like this, but I can't find it now, and it's possible that my memory's failing me.</p>
  
  <p>It's a Win32 application (and a service), so ClickOnce is out (or is it?).</p>
