This is an odd one, I got the upgrade from 10 to 12 (pro), downloaded download assistant, installed Cubase. Download assistant said unable to install for unknown error and to try manual installation direct from folder, did that, said Cubase was installed but cannot find it anywhere on my system. Any help would be appreciated.
Read on another post using the .msi installer for Cubase located in the “additional content” folder fixed the problem. Had a similar problem installing Groove Agent. There was no .msi installer but in this case using the manual installer in the downloaded folder worked.
