thanks for answer

no , I’m newbie on mikrotik operating system. could you please help to install license?

Have a look at this fine manual from MikroTik.
You need to purchase a license after installing RouterOS inside your VM.

small note - without license router will work for 24 hours of uptime, so, if you are testing something, just shutdown the router when you are not using it. SO if you are working 8 hours a day, your installation is good for 3 days then.
