It's been a few years since I wrote one but at least back then windows installers were an amazing mess. We used Wix as an abstraction on top of the underlying libraries (which at the time were still win32, not sure what's happened since). I'm not sure if any progress has been made since but it was a pretty painful experience, especially localization.
