ROW was taken over and renamed after the original mod maker got sick and stopped working on it (sadly he never recovered). it was made for a much earlier version of the game and even if you found a copy of ROW somewhere it would likely cause some CTD issues.
Leo turned ROW over to another modder he trusted and it was renamed and became what turned into Env 5 or PE4 (i forgot which one) but AFAIK one was a reinterpretation of his work and one tried to stay true to ROW settings where the other mod wanted to use different settings because they thought it looked better.
no matter of which of these you liked best they both were great mods with the main differences in water color, smoke, and explosions that i can recall.
they were eventually merged into the Real Environment mod and that is the end result of years of work.
now you know the whole story
