Thanks that worked like a charm, it is a real shame that it requires a work around. I was a bit ticked at first as I had already purchased a bunch of V4 stuff before even installing.

Quote - A couple of people have reported the same thing, I remember hearing a fix being just to create a blank text file in that location and it will get you past it.  Poor of DAZ to keep letting show stopper installation bugs like that out the door, especially after it's been reported multiple times.
