Ray, My first Everything Pak. HD was in 2011.5. The RealTracks were large at that time, but not so many to deal with. I believe it required about three hrs. on a rather slow Sony laptop. My normal up grades have been by CD. Quick, and I keep the disks just in case. Now we have so much more for the same amount of an investment. The RealTracks, RealDrums and everything else require 80 plus GB. I had a problem of some sort with a fresh HD install to a fast i7 HP. I would think 2 or 3 hrs. would be normal. Oh well, I will use the CD up grades next time.-----Leon
