"Library load failed (libgtk-3-0.dll;gtk-3-3.0.dll;gtk-3.dll): The specified module could not be found" while attempting to run on Windows

[Clouud9]

For some reason beyond my knowledge, GTKD seems to be unable to find the GTK Runtime's DLLs on Windows. I've tried building from source as well, but the linker gives a large number of errors saying that there are undefined symbols. Frankly I'm at the end of my tether and I've been unable to find any explanation as to why this is happening, or any potential solution to this issue.

Error Output when running dub run (Installed just through dub):

Currently on Windows GtkD searches the the directories listed in the PATH environment variable for the gtk dll's. And then checks if they have the same architecture (32 vs 64 bits) as the application that is using GtkD.

Alright I just checked it twice. Still the same issue regardless of whether I use the 32-bit or 64-bit version of the runtime. This is for the dub-installed version for the record.

Update: Using this installer, I managed to get a simple example up and running. I'm unsure what the difference is between the runtime on the gtkd website and here, but maybe it will help. At the very least it would be useful to use the installer (if possible) on the website itself. I'll update this thread in case I run into any problems when using more advanced features. The error could maybe have also been due to the fact that I possibly installed the package before the runtime, but I'm not sure if that's exactly what caused it.
