Activation failed on Katalon Runtime Engine

I downloaded KSE and created test suite and generated command and i want to run it on command line.I downloaded KRE and on KRE file path on cmd i paste the command and i getting error Activation failed.

Hi @sub.paudel

What are the email that you used to register an account on Katalon ? The log says that trial license is available only for business email only (non gmail, outlook, etc), so that’s the reason why it’s failing.

so can i update the existing email address to company email.
