Cubase Update. No Changes?

I have the Cubase 8.5.15 Installed.

I just saw the news about Cubase Artist 8.0.40 (service update).

I dont get it. If I have 8.5.15 installed, how can a new update be called 8.0.40?

Furthermore. When I try to install it, it makes no changes and tells me I cannot continue since no changes are made.

Please help/advice .

It is for an earlier version (Cubase 8), not for Cubase 8.5

Ahhh. I keep forgetting that people who stays on 8. 7. etc also needs performance updates.

Do you by any chance know the solution for that problem?
