Built against a new Major version (I have V6)

Hi. I’m a returning user of Rhino, and I only have V6, I skipped V7 because by the time I’ve returned to rhino, V8 is coming out, and I just don’t want to spend 800 SGD to be rendered obsolete by the end of the year. However, Eddy3d for it’s claims that it can “run on V6” in food4rhino, clearly doesn’t work here.

Kindly assist, I will need this program soonest, by today preferable. Thank you!
