Yes I had no problem wrapping the Cycling '74 plugins... all of them. Not sure why you're getting the error but I had no problems with them. It's been a while but I think I manually wrapped them. Just wanted to let you know it is indeed possible.
yeah i got the demo versions of the pluggo plugins and they make my wrapper crash every time and i dont even care about them all i want to do is use Battery 3 in protools but i guess that wont unwrap either. whyyyyy such a waste of money
