Register License not working

Suddenly, our License isn't working.


We've got an angular library and a host application in a single environment. When we run the library and host together, the License (which is in the host application) is no longer recognized and pops this message:

"This application was built using a trial version of Syncfusion Essential Studio. Please include a valid license to permanently remove this license validation message. You can also obtain a free 30 day evaluation license to temporarily remove this message during the evaluation period. Please refer to this help topic for more information."


I've tried recreating a License key, but no change.


This all worked perfectly two weeks ago. We have not altered the required integration code.

The message appears on all controls.

Hi Jason,


Greetings from Syncfusion support.


Syncfusion components are version based components, so you need to generate a new license key for every major release. For example, if you are using v20.1.xx packages in your project and have registered the corresponding license, then the project will work fine without any license issues. If you are upgrading your packages to v20.2.xx then you need to generate the license key for v20.2.xx and register it in your project, to avoid any license issues.


If you are upgrading your packages, we suggest you to upgrade all the Syncfusion component packages that you are using in your project, this will avoid the chances of creating duplicate packages in your project.
Registering the license key in the index.js file is enough.


Also please follow the below steps to install the packages, so that duplicate packages will not install in your project.


1. Delete the @Syncfusion folder from node_modules and the package-lock.json file from the root folder.

2. Clear npm cache at your end.

3. Update our packages to the latest version (all packages should be upgrade to 20.*).

4. Run the ‘’npm install” command to install the node_modules.


If the issue still persists at your end, please share us the issue reproducible sample.

We are using:

    "@syncfusion/ej2-angular-dropdowns": "20.2.39",
    "@syncfusion/ej2-angular-grids": "20.2.39",
    "@syncfusion/ej2-angular-navigations": "20.2.39",
    "@syncfusion/ej2-base": "20.2.39"

  • I deleted and reinstalled the node_modules.
  • Problem solved!


Thanks!
