I can never enter an activation code to the e-licencer control center. I did everything as it told me to do. When I enter the activation code in -elicencer, it shows this error despite I downloaded the latest version of elicencer again and again. Besides, my activation code is in this form: 00000-00000-00000 as 5 by 5. But in e licencer it shows it as 0000-0000- as 4 by 4. I didn’t make it. Please, help. I’m from istanbul.
Start with installing the latest version. Download from here:
Thanks but I did it, download assistant perfectly worked and installed everything coming with the cubase 12 pro package. The software is working well. But I can’t see my software in e -licencer screen unfortunately . It’s empty and I tried many times to download it again. Same response. “It is old”. I donwloaded it from the same link though. 
Cubase 12 and most other products currently being sold by Steinberg don’t use the eLicenser at all anymore.
Thanks. Everybody talked about the e-licencer and nobody told me I don’t need it for 12. Thank you very much.
