I attempt to set up Wordpress inside a Home windows Client with WebPI which supplied by Microsoft.

Everything set up in my client and lastly I saw effective message. having a lunch application link. After I click it I see following error.

Your PHP installation appears to be missing the MySQL extension which is required by WordPress.

How Do I resolve this problem

I requested this at ServerFault Here

Look at your php.ini apply for the right pathways. Without having use of it, request your internet host: http://serverfault.com/search?q=missing+mysql+extension

This is a good utility that may identify issues with your PHP installation in addition to fix them for you personally: PHP Manager 1.1. You may also do the installation with Web PI (the hyperlink to installation is incorporated in the article)
