This page refers to key-based licenses — a legacy license type used in TestComplete until version 15.48. This license type will no longer be available after September 2023. For information on the current, ID-based license type, see SmartBear ID-based Licenses.
A Floating User license allows you to run multiple instances of TestComplete on multiple workstations in the network. The number of instances running concurrently is determined by the license key. If you have a Floating User license, you can start TestComplete only if the License Manager has at least one Platform license that is not currently in use.
If all the Platform licenses are currently in use, TestComplete fails to start and displays an error message notifying you about the problem. In this case, wait until another user finishes their TestComplete session (and, therefore, releases the license), so that you can start TestComplete on your machine.
Alternatively, consider upgrading your license to allow more concurrent users. For more information on upgrading licenses, see Upgrading Existing TestComplete 15 Licenses.
