PHP Error | HTTP Error 500.0 – Internal Server Error | C:\Program Files\PHP\vX.0\php-cgi.exe – The FastCGI process exited unexpectedly

After installing PHP on your IIS,  you might be stuck with the following error :

Http Error 500.0 FastCGI process exited unexpectedly. ”

This error occurs when the Visual C++ Redistributable file to handle CGI process is not present in the system.

To resolve this issue you just need to install proper VC++ redistributable file.

So if you are facing this issue, and if the system does not have proper VC++ version, then just install the version of VC++ supported by the PHP version installed on your system to resolve this error.

List of PHP versions and the VC++ versions supported by it:

PHP version MVC version Supported VC++ version
PHP 7.0 VC 14 Build VC ++ 2015
PHP 5.6 VC 11 Build VC ++ 2012 / update4
PHP 5.5 VC 11 Build VC ++ 2012 / update4
PHP 5.3 VC 9 Build VC ++ 2008

So happy troubleshooting folks . 😉
