PROBLEME CUBASE

I have a huge problem. I have the Cubase elements 7 and I made the update to the Cubase elements 9. Should it remove the Cubase 7 or not ???
On the other hand with the Cubase 9 I had Groove Agent SE and I have huge problems with it. Would anyone know why?

Thanks

No Elements 7 should not be removed by the Elements 9 installation and indeed there’s no need to do so.

Hard to say anything about the issues you had with Groove Agent SE without more details…what problems are you having?
