1. If you have Intel Core CPU, download and install Intel OpenCL drivers. You can find download link here:OpenCL™ Runtime 16.1.2 for Intel® Core™ and Intel® Xeon® Processors for Windows* (64-bit & 32-bit)
2. Open Windows Registry Editor (regedit.exe): press Window+R, type "regedit", click Ok. Find the path of the plugin that has OpenCL error, for example Retouch4me Portrait Volumes:

Change the value of the attribute ailayersFlags
3. Relaunch the program. It should work fine after that.
