Installers have improved a lot the latest years - and authorization shit is more integrated - which were more like separate thing alltogether 2010 with my first contact with Cubase.
Updates of license databases are also integrated into more smooth operation now.
2010 when I were to run a trial - all this was a disaster and I could not even get trial license onto Syncrosoft lock I bought. You had to upgrade eLicenser by yourself and tried on links that were broken, run update of license database by yourself etc. And still it failed, and support could not fix it for me - I could never run the trial. It cost Steinberg at least 4 years of upgrade fees that I never did.
So depending on age of youtube stuff - it can tell very different story.
Still things to improve - like integrating register at MySteinberg so you don’t have to fiddle with that anything. Serials still needs that, even if Steinberg lock was part of install as I recall. Authorizing should be set and forget kind of thing.
