[php] The FastCGI process exited unexpectedly

I am trying to run PHP via FastCGI on a Windows 2008 server.

I followed this installation doc http://learn.iis.net/page.aspx/246/using-fastcgi-to-host-php-applications-on-iis7/ and have checked I completed the steps correclty numerous times.

However when I try to execute a php page i am presented with the following error:

HTTP Error 500.0 - Internal Server Error C:\PHP\php-cgi.exe - The FastCGI process exited unexpectedly

maybe you should try installing VC++ runtime as explained here.

There's a fairly good chance you're missing the correct VC++ runtime for the version of PHP you're running.

If you're running PHP 5.5.x you need to ensure the VC++11 runtime is installed:

Make sure you download and install the x86 version (vcredist_x86.exe), PHP on Windows isn't 64 bit yet.

If you're running PHP 5.4.x then you need to install the VC++9 runtime:

I tried opening php-cgi.exe directly and it gave me a more clear error message.

In my case I had wrong constellation of configurations:

• error reporting disabled
• typo error in the configuration

After enabling the error_reporting it was clear the session_path was pointed to a wrong folder.

"Sad but true"

If you are installing PHP 7.1.14 on windows server 2008 rc2 Enterprise, only thing worked for me is to install microsoft Visual C++ 2015 Redistributable Update 3 from https://www.microsoft.com/en-us/download/details.aspx?id=53587

I was getting this same error installing PHP 7 on Windows Server 2008 R2. I resolved this by installing the Visual C++ Redistributable for Visual Studio 2015.

As the answer of 'sepehr' this issues are because of VC++ Redistributable suitable version for PHP are not installed or need to be reinstalled again.

I faced it before so i'll explain my steps to fix it.

1- Each PHP version is built by a specific Visual C++ Redistributable version like (10, 11,12,14,..) what ever. ((How you know!! look.. ))

• Check back enter link description here The PHP Site then at the left side of this page, look at "Which version do I choose?" then see what version of VC++ is fits your PHP version installed.

• Now YOU HAVE TO Download both of VC++ 32 and 64. and if your PC has it already then Unistall them first. and then install what you downloaded recently bu (first 32 then 64).

- VC download links are exists on the mentioned PHP Site on the left side also.

I hope it helps you.

In my case the problem was coming through the application pool. Try to change your application pool ASP.NET v4.0.

When you run php-cgi.exe from the dos command line, you will get the missing MSVCR110.dll pop up message.

Like Ben said, Get the x86 download for the dll here: http://www.microsoft.com/en-us/download/details.aspx?id=30679

For Issue C:\PHP\php-cgi.exe - The FastCGI process exited unexpectedly.

I resolved this by installing the Visual C++ Redistributable for Visual Studio 2015.(Microsoft Visual C++ 2015 Redistributable Update 3) and Visual C++ Redistributable for Visual Studio 2012 Update 4 in 32 and 64bit versions. and also make sure in php.info file cgi.fix_pathinfo=0 enabled.

For user using PHP 5.6.x follow this link and install the x86 version.

if you have two application like (your app, phpmyadmin) just disable APC extension Hope that fix that issue it's worked with me

After much pain and suffering, turns out I needed to install the "Visual C++ Redistributable for Visual Studio 2012 Update 4 32-bit version", even on my 64-bit server.
