A Floating User license (also known as concurrent license) is shared by a group of users within the same network and allows any user to use the license at one time; the number of concurrent users is limited and determined by the license key. With Floating User licensing, you can start TestExecute only if the License Manager in your network has at least one Platform license that is not currently in use.
This message indicates that all available Floating User licenses are currently in use. In this case, you need to wait until another user finishes their TestExecute session (and, therefore, releases the license), so that you can start TestExecute on your machine.
Alternatively, consider upgrading your license to allow more concurrent users.

The troubleshooter will also help you collect information needed to submit a request to the SmartBear Support Team.
