Latest update broke Titanium studio on windows

I updated titanium yesterday to CLI 4.0.0 and now nothing wants to build

I've tried uninstalling and getting rid of everything but nothing works, I always get this error even when creating a new project.

Node.js Version             = 0.10.13
  npm Version                 = 1.3.2
