Upgrade fail, from cubase studio 4 to cubase 12

I got this message when I tried to install cubase 12. See picture.

I have an old usb stick with a license for cubase4 that I haven’t used for many years. Now it doesn’t seem to work with the license?
I just bought the upgrade today. I used to work on a pc but now Im on a Mac. Does it have anything to do with that?

Did you “Perform Maintenance Tasks” on that eLicenser already? If not I’d give that a try.

Thanks! I think it works now.

Which Cubase upgrade release did you buy, Elements, Artist, Pro?

It seems you took an upgrade that does not match your Cubase Studio release.

It doesn’t matter if you have a PC or Mac.

You should purchase the upgrade from Cubase Studio, not Cubase 4. The verification process will not go through if you don’t have a valid license to upgrade.

Please contact Steinberg Shop Support if you purchased the wrong update.
