Whoa, this mail is over 2 years old, no answers, and I have this same problem now. Just bought Grand 3 and I was totally SHOCKED that installation process didnt even ask which folder the soundbanks should be installed. You just think its ok to install over 30GB of sound samples just like that into system drive? What is wrong with you? Steinberg support, if you think you as professionals, I think this issue should be taken care of.
