This question is just for personal request.......... I am always wondering why the program from Linux cannot install in Windows.....? I know from very simple knowledge, that they are two different OS.......but still they all work on same CPU (same machine/assembly language)...........Is it a problem that windows is 64 bits and Linux is under 64 bits? (this is why Windows program cannot work under DOS, right?) I know that Windows cannot operate on Mac, because the machine language (CPU) is not compatible......right?
