Trial license

I installed a trial version of UIPath Orchestrator 2018.4.5. I tried to add a robot but it is disabled. I noticed that it is not licensed. Where do I find.obtain a license for a trial version?

Have you uploaded License File to Orchestrator?

No. I do not know where to find the license file.
