The FastCGI process exited unexpectedly on Windows Server 2012 R2 with php 7.0.9 x64

I am getting this issue with when I'm trying to host a PHP website on on IIS.

IIS 8.5 (Server 2012 R2) and PHP 7.0.9

When I switch version to PHP 5.3, it works fine. But PHP 7 gives this error.

HTTP Error 500.0 - Internal Server Error C:\Program Files (x86)\PHP\v7.0\php-cgi.exe - The FastCGI process exited unexpectedly
