Problem running php and asp on the same iis website

I installed IIS8.5 

I wanted to run on my website php and asp files. I installed Microsoft® Web Platform Installer (Web PI) it made configuration in IIS in Handler Mapping it added Module mapping *.php with handler FastCgiModule adn path to php;in FastSGI Setting set path to php-cgi.exe, in ISAPI and CGI Restriction was allowed path to php also. 

When I tried to run php file with function  phpinfo(); from my default website i received this error 

HTTP Error 404.0 - Not Found

The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

but my php file is on the right location.

I created new clear webiste without any asp files in his deirctory and I tried to run from there the same php file and it dsiplayed information. But i need this php file to be in exsisting directory.

Thanks if you need more information write me
