Remove "sysadmin@thingsboard.org'" from the database to install Thingsboard

Question

I am trying to install Thingsboard on Windows 10. But I get the error: "org.thingsboard.server.dao.exception.DataValidationException: User with email 'sysadmin@thingsboard.org' already present in database!"

Would anyone please help me to resolve this problem?

Thank you.
