Klanghaus & Cubase 7.5

mm, i dont know it, but,

do a search on your pc for *.vstsound
this will find the folder where your other vstsound files are. copy the klanghaus one into there.
if you have moved your regular vstsounds to another folder already, you should have shortcuts to the files in the original folder. dont forget to make another shortcut for the klanghaus one as well.
-also, do you need to register it on your dongle?
