Licensing FAQ

Is an internet connection required for license validation

No, Internet connection is not required for the Syncfusion Essential Studio license validation. The Syncfusion license validation is done offline during application execution. Apps registered with a Syncfusion license key can be deployed on any system that does not have an internet connection.

Upgrade from the trial version after purchasing a license

To upgrade from the trial version, there are two possible solutions:

• Uninstall the trial version and install the fully licensed build from the License & Downloads section of the Syncfusion website.
• If you are using Syncfusion controls from the npm, replace the currently used trial license key with a paid license key that can be generated from the License & Downloads section of Syncfusion website. Refer to this topic for more information regarding registering the license in the application.

The license registration is not required if you reference Syncfusion scripts from the Licensed installer. These licensing changes apply to all evaluators who refer to the Syncfusion scripts from the evaluation installer and those who use the npm packages form npm

Where can I get a License key

License keys can be generated from the License & Downloads or the Trial & Downloads section of the Syncfusion website.

The Syncfusion license keys are the version and platform-specific, refer to the KB to generate the license key for the required version and platform. Also, refer to this KB to know which version of the Syncfusion license key should be used in the application.

While using the ASP.NET Core controls with the Javascript(ES5) components, you need to register the license key in both the Javascript(ES5) and the ASP.NET core. Since the license is validated at the client side for Javascript(ES5) components and server-side for the ASP.NET core components.

Will the registered license key expire

No, the Syncfusion license keys won’t expire for a particular version and you can continue to use it. So, you won’t face any problems on the live site. If you have used the trial key, it will expire in 30 days and we don’t recommend using it in production.

If you upgrade to newer versions of the Syncfusion packages, you have to generate new license keys and use them.

When to generate new license key while upgrading

You don’t have to generate and change license keys for minor version upgrades. If you upgrade from one major version and another major version, you have to generate new license keys and register in the application.

For example,

• If you upgrade to weekly releases or the SP release in the same major version, you don’t have to change license such as if you upgrade from the 20.1.47 version to 20.1.* you don’t have to change the license keys.
• If you upgrade from one major version to another major version, you have to generate new license keys for the latest version and change in the application, such as if you upgrade from the 20.1.* version to 20.2.*, you have to generate new license keys for the latest version and change in the application.

License registration for multiple developers on your project

Syncfusion license key is a version based and it’s not based on the developer. You don’t have to register different keys for each developer. Just register one valid license key when developing and publishing the software.

Can I use the same key for all the web apps under the project

Yes, you can use the same license key for all the web apps.

Does the license registration access any resources or data

No, the license registration doesn’t access any data or resources.
