I installed trial versions of PowerBuilder 2019 and related Appeon tools to evaluate its web development capabilities. PowerBuilder and SnapDevelop is working fine. But, I could not activated Power Server. After installation I logged in to http://localhost/AEM/ with username:admin, password:admin credentials. Then I used my trial account credentials to activate Power Server. And I got "Error code: 1009, error message: Cannot find a valid license." error message. What is the correct way of activating Power Server? Is it possible with trial product versions.
