Need nuendo lic to activate

need nuendo lic to activate nuendo 11 how to make this happen will someone please help

Should be available in you user account, I guess:

Sign in

If you already own a Nuendo 11 licence, plug in the USB eLicenser containing the licence.

If you do not already own a Nuendo 11 licence then you will have to buy one second-hand. Steinberg only sells Nuendo 13 licences, which will only activate versions 12 and 13.

Not working for me either, although I have Nuendo 12 license which I want to update.
