Test Studio Licensing Server

Test Studio uses a per machine licensing scheme, which requires Internet connection to be activated. To ease the process of activating and distribution of licenses across multiple users Test Studio provides a Licensing server application, which allows floating management of the purchased licenses.

The below article describes how the Licensing server works and the process of installing and configuring it.

How the Test Studio Licensing Server Works

The Licensing Server application requires to be installed on a machine, which has active connection to the Internet. This is the component, which will contact the Telerik license database to get information for the active purchased licenses, which can be used under a Telerik account.

The Licensing Server application requires a valid Telerik account to be logged in. This account should belong to the license holder user or to a user assigned as License Manager for the purchased licenses in the Manage Test Studio Activation Keys section in your Telerik account.

The machine, on which you activate Test Studio, requires connection to the configured Licensing Server machine only (may not be connected to the Internet). Start the installed Test Studio, choose the option to activate a license through the Licensing Server and enter the Licensing server address. The license gets activated, if there are free slots.

Once you exit Test Studio on your local machine, the license remains reserved for the next 5 minutes. After that it is released and can be activated on another machine, which has access to the Licensing Server. Next time when you start Test Studio on a machine, which is already connected to the Licensing server, it takes a license automatically, if available.

Install and Configure the Licensing Server Application

The Licensing server is a separate application and has its own installer file, which can be downloaded from your Telerik account.


Once you have downloaded the Test Studio Licensing Sever *.msi file, double click it to start the Installation wizard.

Use the Licensing Server to Activate Test Studio License

The option to use the Licensing Server is not visible by default. To be able to see it in the License Activation wizard, a Windows Administrator account needs to add a registry key to enable the Licensing Server activation.

Enable Licensing Server Activation Option

To enable the Licensing Server option in the Activation wizard, you need to add a registry key in the machine registry.

  1. Type 'RegEdit' in the Windows Start menu and run the Registry Editor.
  2. Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Telerik\TestStudio.
  3. Create a new key of type DWORD and name it EnableLicensingServerConnection.
  4. Set its value to 1.


The key can be added before installing the Test Studio product. If Test Studio is already installed, you can first deactivate the current activated license, then add the registry key. Upon starting Test Studio again you will be prompted to activate a license and the option to use the Licensing server will be available.
