No activation code send Dorico trial version…not in Spam or anywhere… 
Hello Jobinix and welcome to the forum!
There is no Dorico 3 trial yet… You are trying to have a Dorico 2 trial code, right?
Ah, thank you. I went to the Dorico 3 page and clicked on the “Download Trial Version” buttom that send me via via to the Dorico 2 trial page. You’re right. Steinberg should change that. Ok, I found out it will be available in a few weeks.
I’m waiting for my own activation code for the trial too (of v2). Not arrived as of yet.
