PHP5.5 cannot run on IIS7.5. it works normally after version 5.3 is used.

PHP5.5 cannot run on IIS7.5. after using PHP5.5, a front-end engineer in the normal department needs to deploy PHP under IIS and install PHP5.5.14. after the deployment is complete, the error 500 is always prompted when you open the page: an unknown FastCGI error occurs.

I searched the internet for half a day, and some said that the VC11 for PHP 5.5.14 was not installed, so I went here to download and install it. the problem persists.

Continue to search, saying that PHP5.5 has started and does not support running on xp or win2003. it only supports Windows 7 7 and above, but this is Windows 7.
Then try to double-click to run c: \ php5.5.14 \ php-cgi.exe, the results pop up the prompt "c: \ php5.5.14 \ php-cgi.exe is not a valid Win32 application", use this to search, "This is a version Issue. PHP5.5 must run at least 6.0 in the operating system version? My WIN7 version is 6.1.

Later, I tried to download php5.3.58.first, double-click php-cgi.exe, and confirm that it can be executed without reporting an error. then, I modified the program ing in IIS to point to the cgi of 5.3.5, and php ran smoothly.

Postscript: who told me that PHP5.5.14 only supports WIN7 and above?
