OK I am taking a line out of my httpd.conf file. Also using the C:\php folder is SUICIDE! If another hack comes available then they can know where your source lies. Which is bad. Check this line out and add all 3 to the END of your httpd.conf file. I included the last line of the httpd.conf so you can see where and how to place it.
</VirtualHost>
ScriptAlias /php/ "c:/php/"
AddType application/x-httpd-php .php
Action application/x-httpd-php "/php/php.exe"
ASSUMING everything was placed in C:\php folder. If so then you are good to go.
Check that, save, and then restart server. See what it says and get back to us. Thanks!
