Convert prepaid key to licence Key

hi,
I have 2 prepaid license keys (x86/RB/CHR) available (Mikrotik Certifications) but i can’t use it for my CHR.
In CHR system license print i found System id, but the web page ask me Software ID. Can you help me?

Click on the link “our support” on that page.

You do not need to convert this keys in order to use them with chr. Just go to System-License, press Renew License and that’s all

CHR keys are different and unrelated to x86/hardware device licenses. This menu is not for CHR.

To convert a CHR trial license to a fully licensed one, go into the menu “All CHR keys” and click “Upgrade”. There you will be able to use the Prepaid key

in menu “All CHR Keys” i have this:
You do not have any active CHR licenses!
and in my vps chr license menu: This System ID is not valid for license.

i have same problem and i found this topic, so this is not solved yet ?
