why I can not buy Cubase 10 pro from Serbia?

Hi and welcome,

How do you know, you cannot buy it? What happened? Any message displayed? Can you buy from a local dealer?

I’m sorry to say that currently, the Steinberg Online Shop does not ship to Serbia. This applies to boxes and downloads as well.
Please check with the local distributor. More information here:

Dear Steinberg,

Will people from Serbia be able to buy download versions of your products before the end of this spring sale or at any time?
