Trouble running local WordPress in Google App Engine

Following these instructions.

Installed MySQL, Python and Google App Engine PHP SDK on a Windows 8 PC. Perfect!

Created an app for WordPress, created database and user on localhost and edited WordPress config accordingly.

Started the app in the Google App Engine Launcher. Clicking Browse leads to blank page at http://localhost:8080/

Hmmm…

Checked logs, found

Pretty certain the Python for Windows package I used included PIL. Not sure where to go from here…

If I go to http://localhost:8080/wp-admin though, I get

Warning: chdir(): Invalid argument (errno 22) in C:Program Files (x86)Googlegoogle_appenginegoogleappenginetoolsdevappserver2phpsetup.php on line 42

Warning: require(wordpress/wp-admin/wp-admin/install.php): failed to open stream: No such file or directory in C:Program Files (x86)Googlegoogle_appenginegoogleappenginetoolsdevappserver2phpsetup.php on line 103

Fatal error: require(): Failed opening required 'wordpress/wp-admin/wp-admin/install.php' (include_path='C:UsersCsillamVilagDocumentsdevelopment-appenginearcfestesmintak;C:Program Files (x86)Googlegoogle_appenginephpsdk') in C:Program Files (x86)Googlegoogle_appenginegoogleappenginetoolsdevappserver2phpsetup.php on line 103

In the error returned at http://localhost:8080/wp-admin/ I see /wp-admin/wp-admin/install.php

Obviously install.php cant be found. It is in /wp-admin/ not in /wp-admin/wp-admin/
Not sure how to fix that.
