# Error when Upgrading PHP on Windows

 * Hello,
 * I have a multi-site install on my server. I’m currently running PHP 5.2 and I’m
   trying to upgrade to PHP 7 using IIS. I added the PHP 7.1 folder to the server
   in the Program Files (x86) folder along with the other PHP 5.2 folder. I went
   into IIS and registered the new version and added it. The PHP executable is pointing
   to C:\Program Files (x86)\PHP\v7.1\php-cgi.exe. I ran the Check phpinfo() and
   everything checks out just fine. I even added the appropriate Handler Mapping(
   or so I think).
 * When I go to the URL, which is [http://dev.fcps.net](http://dev.fcps.net), it
   says:
 * The dev.fcps.net page isn’t working
    dev.fcps.net is currently unable to handle
   this request. HTTP ERROR 500
 * Does anyone know what may be the issue.
