I have installed php5.2 on IIS 5.1, windows XP, with FastCGI. I believe all IUSER permissions set for c:\php\phpini and c:\php\php-cgi.ini. /Software/PHP Register key modified to include string IniFilePath=C:\php, environment variable path and PHPRC path set to C:\php, restarted IIS several times. Still, phpinfo() configuration path points to C:\windows, and loaded configuration = NONE. Anyone help? This is stopping phpmyadmin from working - error is: "Cannot load mysql extension. Please check your PHP configuration". Hope someone can help. Thanks

    Have you restarted the entire Windows operating system (not just IIS) after making the registry changes?

      Yes - I have restarted Windows and it still did not work. There must be something that I am missing. I am very open to suggestions. Thank you for your help.

        I tried copying php.ini to my windows directory, then restarting IIS - no avail. I then restarted my windows system - still not working.

          I uninstalled php version 5.2.x, deleted all files in the C:\php directory, installed the new php version 5.3.x, restarted IIS and all works fine now. I am guessing there are some compatibility issues with IIS 5.1, WIn Xp, and PHP 5.2.x.
