Setting Up Your Kendo UI for jQuery License Key

This article describes how to activate the Kendo UI for jQuery components by installing a new personal license key and how to replace an already expired one.

Kendo UI for jQuery is a professionally developed library distributed under a commercial license. Using any of the UI components from the Kendo UI for jQuery library requires either a commercial license key or an active trial license key.

To activate the Kendo UI for jQuery components:

1. Download a license key.

2. Install or update your license key file in your project.

Downloading the License Key

To download a license key for Kendo UI for jQuery, you must have either a developer license or a trial license. If you are new to Kendo UI for jQuery, sign up for a free trial first and then follow the steps below.

1. Go to the License Keys page in your Telerik account.
2. Click the Download License Key button.

Starting with the 2025 Q1 release, the name of the downloaded file changes from kendo-ui-license.txt to telerik-license.txt. This change is required as all Telerik UI and Kendo UI products now use the same licensing mechanism with a common license key. See the Handling License Key File Name and Environment Variable Name Changes in the 2025 Q1 Release KB article for more details.

Installing or Updating the License Key

Whenever you purchase a new Kendo UI for jQuery license or renew an existing one, always download and install a new license key. The new license key includes information about all previous license purchases. The procedure for the installation of a new license key and update of a license key is the same:

1. Copy the downloaded telerik-license.txt license key file to your home directory. This makes the license key available to all projects that you develop on your computer.

   • For Windows: %AppData%\Telerik\telerik-license.txt

   • For Mac/Linux: ~/.telerik/telerik-license.txt

     Alternatively, copy the telerik-license.txt license key file to the root folder of your project. This is the folder that contains the package.json file. This makes the license key available only to this project. Do not commit the file to source control as this is your personal license key.

2. Install @progress/kendo-licensing as a project dependency by running:

npm install --save @progress/kendo-licensing

or

yarn add @progress/kendo-licensing

1. Activate the license by running:

npx kendo-ui-license activate

or

yarn run kendo-ui-license activate
