My suggestion for PCWinsoft is that they should learn the correct placement of executables in the installation folder and not in the userdocuments subfolder where there is no protection of the executables from write access and forces the program to have to be installed multiple times if there are more than one user accounts on the system. I’d also suggest they abide by the licenses of the third party programs they often currently abuse for example FFMPEG.EXE they always use the GPLv3 build but that is incompatible with a closed source GUI like theirs, they should re-build it with the LGPLv3 build switches AND acknowledge that they are using it, provide a copy of the license file after all many of your programs you sell could not function without the unauthorised functionality of the FFMPEG.EXE program that deals with the media files for you.
