How to run Dorica as a Demo-version

I’m very interested in Dorica. Now I use Sibelius. But it is realy nessesary to Test the programm first time. I downloaded Dorico and installed it. But if I try to start it asks me for a licence key.
How can I start it as a Demo-Version.

There’s no trial version of Dorico available as yet. The trial version will be available before the end of November, at the same time as the forthcoming 1.0.10 update.
