I try to install WordPress in a Windows Client with WebPI which provided by Microsoft.
Everything installed in my client and finally I saw successful message. with a lunch application link. When I click on it I see following error.
Your PHP installation appears to be missing the MySQL extension which is required by WordPress.
How Can I resolve this issue
I asked this at ServerFault Here
Check your php.ini file for the correct paths. If you don’t have access to it, ask your web host: https://serverfault.com/search?q=missing+mysql+extension
