Title: Installation Problems – Windows Server 2012 R2 Last modified: August 30, 2016 --- # Installation Problems – Windows Server 2012 R2 * Resolved [trickyninja](https://wordpress.org/support/users/trickyninja/) * (@trickyninja) * [10 years, 9 months ago](https://wordpress.org/support/topic/installation-problems-windows-server-2012-r2/) * Hello, I stood up a new Windows Server 2012 R2 machine and attempted to use the following guide: [https://codex.wordpress.org/Installing_on_Microsoft_IIS](https://codex.wordpress.org/Installing_on_Microsoft_IIS) I ran the Web Platform Installer and everything showed completed successfully. However, I noticed it did not install WebMatrix like the guide said and when the installer closed, it attempted to open my site in IE. When the browser opened, I got an HTTP Error 500.0. I tried creating a simple php test page and that did not work so I’m assuming it may be related to the php configuration. * I wanted it in the web server root so that when the site is visited it goes straight to wordpress instead of mysite.com/wordpress/. This Web Platform installer seemed like a simple out of the box install with little work so I thought I’d give it a try. previously I have always done manual installs. * Does anything in the details below stand out? I am able to launch MySQL command line and interact with the database and the files are in the wwwroot folder for wordpress. I’m thinking PHP but don’t know where to start. * DETAILS: * ``` HTTP Error 500.0 - Internal Server Error C:\Program Files (x86)\PHP\v5.5\php-cgi.exe - The FastCGI process exited unexpectedly Detailed Error Information: Module FastCgiModule Notification ExecuteRequestHandler Handler PHP55_via_FastCGI2 Error Code 0x000000ff Requested URL http://localhost:80/index.php Physical Path C:\inetpub\wwwroot\index.php Logon Method Anonymous Logon User Anonymous ``` * IIS Version: 8.5.9600.16384 PHP Version: 5.5 MySQL Version: 5.1 Viewing 4 replies - 1 through 4 (of 4 total) * Thread Starter [trickyninja](https://wordpress.org/support/users/trickyninja/) * (@trickyninja) * [10 years, 9 months ago](https://wordpress.org/support/topic/installation-problems-windows-server-2012-r2/#post-6394485) * Update. I have tried reinstalling a new server and following the process again with exact same results and exact same error. This Web PI shows “successful” but is failing to do its job properly somewhere along the way and the site will not work. * Thread Starter [trickyninja](https://wordpress.org/support/users/trickyninja/) * (@trickyninja) * [10 years, 9 months ago](https://wordpress.org/support/topic/installation-problems-windows-server-2012-r2/#post-6394601) * Still no response here. Hoping for some help. I tried a fresh server and installing IIS first and then using the Web PI tool for WordPress and STILL same exact error. * [catacaustic](https://wordpress.org/support/users/catacaustic/) * (@catacaustic) * [10 years, 9 months ago](https://wordpress.org/support/topic/installation-problems-windows-server-2012-r2/#post-6394603) * I’d suggest that you try to do a manual install instead of using the Microsoft installer. Use what’s installed there for Apache, PHP, MySQL, but download the WordPress ZIP file and follow the [installation instructions](http://codex.wordpress.org/FAQ_Installation). That way you’ll see what’s going on for yourself. * Just as a note, there’s some automated installers that work, and some that don’t. Most of them still limit you to whatever version of the system that they’ve installed, so any recent security updates aren’t able to be installed, which can lead to vunerable sites. I still have yet to find one that works as well as installing and maintaining systems yourself. * Thread Starter [trickyninja](https://wordpress.org/support/users/trickyninja/) * (@trickyninja) * [10 years, 9 months ago](https://wordpress.org/support/topic/installation-problems-windows-server-2012-r2/#post-6394604) * Thanks for the response Catacaustic. I just solved the issue about 10 minutes ago. * I found this post that suggested running php-cgi.exe from command line which helped identify the missing piece, which was MSVCR110.dll: [http://forums.iis.net/t/1149374.aspx?C+PHP+php+cgi+exe+The+FastCGI+process+exited+unexpectedly](http://forums.iis.net/t/1149374.aspx?C+PHP+php+cgi+exe+The+FastCGI+process+exited+unexpectedly) * Then I found this post to resolve it. I had installed the 64-bit version of the redistributable instead the 32-bit version. It seems the Web PI is not installing this and it seems to be a requirement for 2012 R2: [https://www.interactivewebs.com/blog/index.php/general-tips/windows-2012-r2-cprogram-files-x86phpv5-6php-cgi-exe-the-fastcgi-process-exited-unexpectedly-php/](https://www.interactivewebs.com/blog/index.php/general-tips/windows-2012-r2-cprogram-files-x86phpv5-6php-cgi-exe-the-fastcgi-process-exited-unexpectedly-php/) * TLDR, if you get the same error I did, try running php-cgi.exe from the command line with a test PHP page and then install the 32-bit version of the C++ redistributable above and it worked perfectly after that.
