This page refers to key-based licenses — a legacy license type used in TestComplete until version 15.48. For information on the current, ID-based license type, see SmartBear ID-based Licenses.
To use TestComplete, you must have a valid license. TestComplete automatically performs a license check at startup and during the run. If it fails to check the license, it will display a message notifying you about the issue.
You can try resolving the problem by using the Licensing Troubleshooter on our web site:
The troubleshooter will also help you collect information and submit a request to the SmartBear Support Team. When submitting the request, please specify the exact error message you see. To get it, click the header of the message box and press Ctrl+C.
