How to activate cubase le 10.5 on old mac

I’v a printed card of access code for cubase le 10.5 with my purchased device.

while enter the access code into the steinberg download assistant, it just add the latest version cubase le 12 into my downloads, it requires macos 10.14.6 to install, but my computer is old and it must stay within macos 10.13.6.

so how can I manual add old version cubase le 10.5 into my downloads?

if I manual download cubase le 10.5, it can be installed but failure to activated.
it does not accept 25 digits download access code.

or how can I convert my download access code to Activation Code?


You would need Cubase 11 license for this. Please get in contact with your local Steinberg support.
