I've been trying to get Makerbot desktop 3.6 to run on a fresh Windows 7 install, and it won't work no matter what I do. Makerbot support has no clue, and they can't help me. I installed the latest version of python before I installed it, and the print button is greyed out. I can export but it will only export as a Makerbot file, and won't slice. Do I need to install skeinforge?
