hi thank u for reply.
I install it from downloaded file from steinberg web site.
I didn’t install nothing else apart cubase ai8 and the upgrade.Do I must install something else?
thank u very much
2.6 GB… I would expect more. The full Cubase Pro 8.5 has 11GB, but there are more sounds, and also Groove Agent One… Did you download it from your MySteinberg > Downloads?
