Hi Michael,
I'm struggling with the same issue. Any progress on possible workaround ? Actually I got the Developer Toolkit working on Windows 8.1 & VS.2013 Premium (with latest updates), but on my production environment W7 64b & VS.2013 I'm having problems...
It's really a pity that this great tool is not having support with the latest Visual Studio.
Best regards
Ville
