ursa: %1 is not a valid Win32 application

[Dr. McKay]

I'm trying to develop an application using node-webkit, but one of the native modules that I need, ursa, will not work.

I'm aware that I need to build native modules using nw-gyp, which I have done. All of the other native modules work fine, but when I try to require ursa, I get this:

Error: %1 is not a valid Win32 application.

D:\Libraries\Documents\Repos\Haze\haze\node_modules\ursa\bin\ursaNative.node

What am I doing wrong? I'm using node-webkit version 0.8.5.
