I installed PHP (IIS-Aid PHP installer), but was not able to get it to work. When I tried to access a file called PHPinfo.php, I was told there was an error #500.21,
"HTTP Error 500.21 - Internal Server Error
Handler "IIS-Aid Easy PHP 5" has a bad module "FastCgiModule" in its module list"
How can I best fix this? I have limited programming knowledge, (I am familiar with HTML), and want to learn to use PHP on my websites.
