I had the same problem, and this advice worked....
One thing i want to point out is, that you have to fill out the Admin Password in the System Preferences window.
I didn´t do that at first and had this same problem
Your absolute path seems a bit short. Generally it should be something like etc/usr/local/apache/htdocs/ or somesuch. You'd have to check with your host for your absolute path.
I've not tested on a windows based server. but I would think that if windows is running apache/php/mysql it should be fine. Unless of course the server you are using is not running Apache but some Windows based product.
