I installed Google App Engine. When I File->Add Demo Application->python->guestbook, and try to run it, a yellow triangle appears with an exclamation mark. I get this error message also:

I think it should use Python 2.7 that I have installed. Why does it talk about Python 3.4? I have the path to python 2.7 in path system variable. I'm using Windows 8.
