Unable to start Dorico 5 trial version

I downloaded the trial version of Dorico 5. The error is the same: the program does not start. I tried all possible things. I did not receive the download code. However, in an email, it is written that it is unnecessary. I’ve reinstalled everything multiple times and restarted my computer at least 20 times today, and it won’t work. Reading the forums, this is a terrible problem. I don’t trust this program after this because if there are so many complicated problems at the beginning, what will happen later?

I’m sorry to hear that you’ve been unable to start the Dorico 5 trial version, Sandor. Are you on Windows or macOS? What happens when you double-click the Dorico 5 icon to try to start the application?
