Cubase Intallation based on upgrades/updates

Hello everyone,
I upgraded/updated Cubase from 4.0 to 9 versions. At MySteiberg account, at Download tab, I have got Cubase 9 (10.5 GB). My question is, do I have to install all previous versions before installing C9 or can I install C9 at once (I mean, does C9 contain components of all previous versions) ? (As I know, upgrades/updates ovewrite previous version’s files, the same happens with eLicencer dongle). Thx for any help.

Just install C9. The 10GB installer has everything.

thx for your valuable response :slight_smile:

You can run older versions with the updated key, it will not overwrite your old version.
