Extra activation

Good afternoon, 

I have a Trados 2019 license which includes an Extra Activation (please see image below).

I need to use that extra activation in a different laptop, but I can´t manage to use the extra activation.

In the end, I had to deactivate my main license in order to install it in the second laptop, but I do need both.

Does anyone know how can I use the extra activation? I doesn´t seem to work...

Thanks a lot!

Mariluz
