to install PHP 4.0.3 on window2000

Hy I'm trying to install PHP 4.0.3 with IIS. If I choice the php.exe in home_directory tab, when I run http://my_ip/file.php I obtain: "Errore CGI L'applicazione CGI specificata non ha restituito un insieme completo di intestazioni HTTP. Sono state restituite le seguenti intestazioni:" which in english should sound : "CGI errors , application doesn't product the HTTP headers". If I instead use the php4isapi.dll of SAPI files when i run http://my_ip/file.php I obtain : "Warning: Failed opening 'c:\inetpub\wwwroot\phpinfo.php' for inclusion (include_path='c:\inetpub\wwwroot\phpinfo.php;c:\winnt\system32\inetsrv\php\ ') in Unknown on line 0" thank you _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp
