Heya!
I just started the lecture but already installed Blender 2.78 previously which worked flawlessly. By the time I got here and started Blender however I saw the command prompt running infinitely and nothing happened.
Nor the problem or the solution seem to be posted here (Did I miss it?) so just to be safe I share what worked for me in case someone would encounter the same problem.
