Focus Magic portable PAF v4.02a (18 Nov 2016) gives "Internal Error No 9142" whenever the Traffic Light icon (or 'Menu: Image > Start Image Processing') is clicked. The error appears regardless of the filter or input image used. As a result, no image can be processed.
The same error also pops up when 'Menu: Help > Registration' is clicked.
Might the binaries in the PAF be corrupted ? Tested on Win 7 x64.
