VV are you on Win 8 or Win 7?
I'm on Win 8 Pro...and, while they work fine IN a DAW (as a VST) the Stand Alone IK Products
(all of them) don't recognize the QC Driver....
ALL of my other Stand Alones..NI, etc....have no issues...just the IK stuff..
PT11 did not see my QC driver at all....and, it would crash and burn before I even got
to really do anything....it would crash and burn just closing a project...
That's enough issues right out of the gate for me to say "wait and see"
