I have the codes :-) will confirm it soon myself  ;)

Thanks for answering. Unfortunately both hints - other browser, other machine - give me the same "wrong" key I already had tried.

I would be interested in what you have and how Rigol implemented it.

All I have is the trial license keys for my MSO1104z (all options excluding bandwidth upgrade and 500uV resolution) which Rigol kindly sent me as some sore of student bonus. I entered the keys through SCPI commands into the scope and they added 36 more hours to the remaining trial time. I wondered since the scope has no RTC and permanent license storage (not sure about this one yet), i can uninstall and then re-install the same trial licenses and achieve 36 trial hours cycles forever. 

RIGOL please don't read this post :D

Hi all,
I'm trying to unlock MSO1074Z with expired trial license with no luck so far.
A while ago quertymodo had a theory that keys are get locked some time after logo disappears which sounds credible to me.
If someone still has a correct dump could you please try to compare relevant info from it (136 bytes starting at "01 00 84 00 10 00") with unsuccessful dump or just some other dump made later to prove the theory?
Thanks.
