Problems With License Activation

Applies to AQTime 8.81, last modified on January 18, 2022

You may face this problem if AQTime encounters an error when activating your license. The licensing procedure includes the following steps:

  1. AQTime’s licensing subsystem transfers the license key to the Sentinel LDK License Manager service.

  2. The Sentinel LDK License Manager service forms an activation request and sends it to the SmartBear web site (addresses and, port 443).

  3. Then the service receives the activation code in response and activates AQTime.

If the activation fails, this means that an error occurred on one of these steps. AQTime will display a message box notifying you about the problem. Below are some recommendations for resolving typical problems:

  • Make sure the Sentinel LDK License Manager service is running on the License Manager PC. The service is started automatically after the License Manager utility or AQTime is installed. If this service is not running, activation is impossible.

    To determine whether this service is running, open the Control Panel > Administrative Tools > Services window and see if the services list contains the Sentinel LDK License Manager service and that the service is running.

    If the service is not running, try to start it. If this does not help, reinstall AQTime and try again.

  • Check if you activated your license on a physical computer. AQTime licenses cannot be activated on virtual machines. For information on workarounds, see Using AQTime on Virtual Machines.

  • Check that your License Manager PC has an Internet connection:

    • Verify that you have a working Internet connection. Check that the network cable is connected to your computer and check that you can open web sites (for instance, you can try opening

    • Check that the firewalls or proxies running on your computer and local network allow activation requests to the URLs and, and port 443. To determine whether a firewall (or proxy) blocks the port 443, try connecting to the My SmartBear section of our web site (

      Ask your network administrator for help with configuring the firewall or proxy settings, if needed.

    • Some proxy servers and firewalls may require that you specify a user name and password for the connection. If you do not specify them, the activation will fail.

      Please ask your system administrator on the proxy server specifics. If your proxy requires authentication, try activating the license again and enter the proxy user name and password in the License Activation wizard.

  • The activation fails if the license key has already been used earlier. For information on how to resolve this problem, see The License Key Has Already Been Used for Product Activation.

  • AQTime activation fails if you specified invalid activation data. For information on how to resolve this problems, see The Activation Information Is Invalid.

    If you are using a Floating User license, you should activate it on the License Manager PC only. There is no need to activate it on other workstations, on which AQTime instances will run.

If you are unable to activate your AQTime license for some reason, contact our Support Team.
