RB433+r52hn 802.11n missing

Hi all.
I’m not able to enable N mode on this wlan interface.
Current firmware is 6.41.

HW-INFO is that:
interface: wlan1
ranges: 4920-6100/5/a,a-turbo
2192-2507/5/b,g,g-turbo
2224-2539/5/b,g,g-turbo
tx-chains:
rx-chains:

Tried this https://wiki.mikrotik.com/wiki/802.11n_Setup_Guide but Update license failed. Any help, please?

Are you sure, you have R52Hn? See my rb433 + R52Hn

Damn, you are right!

They give me 5 of this, and two of them are rb433+r52, not “Hn”!
Thanks!
