I take it you're talking about the gtk runtime?

Any idea what the difference is?

I found this: https://blogs.gnome.org/nacho/2014/08/01/how-to-build-your-gtk-application-on-windows/
which looks more or less relevant. Perhaps I'll try scraping off the runtime and reinstalling.

This sounds like it could also be used for packaging and distributing GtkD applications. Have you tried it? If not this one, do you know of one?
