Thanks in advance...

In windows 10 64-bit. There is some kind of solution with using

        os.add_dll_directory(full_path)

before calling

        self.__DTKLPR = cdll.LoadLibrary(DTKLPR5Lib)

but this solution is not working in Ubuntu. Because add_dll_directory is supposed to only windows. (Based on information in its documentation)
