Apache and PHP problems on Windows?
Use WAMP If you must use Windows

.
WAMP is Free and Open Source.
You will have your WB site running in 5 minutes.
I did my experiment on XP Professional.
Here is a link to the WAMP project:

Installation: * Install WAMP
* Set password for MySQL
* Rename the index.php from the WAMP install to control.php
* Unzip the contents of the WB zip file into the www directory
* Run through WB setup

The WAMP control panel makes administration easy
