During the installation process, when I run php-cgi.exe from the command line, I get an error about a missing MSVCR110.dll like this:
How do I fix this?
You need to install a Visual C++ Redistributable.
For PHP 5.5 or 5.6, you will need to install Visual C++ Redistributable for Visual Studio 2012. Install the x86 version (you should be using an x86 build of PHP; the x64 build is experimental and not suitable for production use).
For PHP 5.4, you will need to install Visual C++ Redistributable for VS 2008 x86.
PHP 7 is not yet supported by DeskPRO.
