My god that takes me back, I would say no as mitsubishi now use & have used badged HMI/Scada packages for some time.
By the way I was one of the first people to use this even met the designer (it was still being developed then).
It's probably a bit like AFE that was an old dos system however they did do a windows version but mihg as far as I know never was so converting the graphics is probably more of a job than re-writing the whole thing.
