title: IIS 7.5 PHP failure "The FastCGI process exited unexpectedly"
body: <p>I've been attempting to get PHP working with IIS 7.5 and have hit a bit of a roadblock. Whenever I try to load the page I get the following error:</p>
  
  <p>"HTTP Error 500.0 - Internal Server Error
  C:\Program Files\PHP\php.exe - The FastCGI process exited unexpectedly"</p>
  
  <p>Module  FastCgiModule</p>
  
  <p>Notification    ExecuteRequestHandler</p>
  
  <p>Handler PHP_via_FastCGI</p>
  
  <p>Error Code  0x00000000</p>
  
  <p>Requested URL   *http://localhost:80/index.php</p>
  
  <p>Physical Path   C:\inetpub\wwwroot\index.php</p>
  
  <p>Logon Method    Anonymous</p>
  
  <p>Logon User  Anonymous</p>
  
  <p>Failed Request Tracing Log Directory    C:\inetpub\logs\FailedReqLogFiles</p>
  
  <p>I've modified the PHP.ini file as required for use with IIS, and have also switched it to verbose mode. There isn't any log fiel in C:\inetpub\logs\FailedReqLogs, and none related to this error in the other log files generated.</p>
  
  <p>I've tried the other fixes I've found here and elsewhere but nothing's been successful so far.</p>
  
  <p>In some detail these were:
  re-checking PHP.ini
  Setting up fastCGI to work with PHP in IIS (configuring it to load the php.exe)
  Trying WinCache as the execution method.</p>
