Did the examples compile correctly? (You really must compile and understand the examples before trying something new.)
Sounds like something in the new add-on template is not set up to find the path to the Graphisoft resource compiler. If the examples compile, then either strip one down and use that for your project, or track down the different in project settings between the working example and the new add-on.
I have not tried a fresh add-on from the 12 kit on Windows, only the examples. So, it is possible that the add-on template (as the Mac one) expects your new add-on to be saved in a folder that is a sibling to the Examples folder in the devkit hierarchy (using relative paths to find resources). Try that.
Cheers,
