谷歌应用引擎错误http_runtime.py:409无法连接到端口NNNNN上的运行时

As of today January 12, 2014 I downloaded and installed the latest copy of Python and Google App Engine, all 32 bit on my windows 7 64 bit. I tried to use both the command line and the GUI to launch the simple hello world application and I get the following logs with an error at the end:

2014-01-12 01:13:35 Running command: "['C:\Python27\python.exe', 'C:\Program Files (x86)\Google\google_appengine\dev_appserver.py', '--skip_sdk_update_check=yes', '--port=8080', '--admin_port=8000', 'C:\GoogleAppRoot\app1\engineapp']" INFO 2014-01-12 01:13:39,131 devappserver2.py:660] Skipping SDK update check.

My PHP Code (main.php):

<?php
echo 'Hello world!';

My App Code (app.yaml):

application: engineapp
version: 1
runtime: php
api_version: 1
threadsafe: yes

handlers:
  - url: /favicon\.ico
  static_files: favicon.ico
  upload: favicon\.ico

- url: .*
  script: main.php

Please help, I can't really find something that can really in this, this is my first time and I need a jumpstart help, I have no idea why it throws away an error for a very simple code.
