You may face this problem when you are trying to activate the product using the license key that has already been used earlier.
Each license key can only be used once. After you successfully activated a TestComplete license on one computer, you cannot use the same license key to activate it on another computer.
If you have a Floating User license and face this problem, then perhaps you have activated your license on another computer and are now trying to activate it using the same license key on another computer. There is no need to do this. If you have the Floating User license, you need to activate TestComplete on one computer only. This computer will become the License Manager PC and will control the use of TestComplete instances in your network. There is no need to activate TestComplete on other workstations. You can simply install and use it there.
You will also encounter this problem if you moved the license to another PC and did not deactivate it on the previous License Manager PC properly. To move the license, it is not enough to uninstall TestComplete. Before uninstalling you need to “unbind” your TestComplete license from the current License Manager PC. You do this by applying a special file to the License Manager. For detailed instructions on this, see Deactivating and Moving Licenses.
