Your graphics card driver is out of date or was replaced by a generic Windows driver during a recent update. Please go to the graphics card manufacturer’s website and download and install the newest driver. If your graphics card manufacturer has no OpenCL support at all, you can install Intel's OpenCL driver from here: https://software.intel.com/en-us/articles/opencl-drivers#win64
