Difference between the Unlock key and Licensing key

Platform: Miscellaneous |
Control: Install and Configuration

The unlock key and the license key are used for difference purpose.

Installer unlock key


The unlock key is used to install the Syncfusion offline installer and the key starts with ‘@’ ends with ‘=’.  All Syncfusion installers require the unlock key or Syncfusion account which generate the unlock key to install on your machine. If the key is invalid, it will not allow to install. The unlock key can be generated from the License & Downloads section of the Syncfusion website.

The option to generate a unlock key

Refer the screenshot for applying the Unlock key.

The generated license key should be used in the application to remove the licensing exception message. Refer the Licensing help document to register the licensing key in different platform applications.

Hi, My license key is not working even if it is integrated into main.ts as written here for the Angular apps https://help.syncfusion.com/common/essential-studio/licensing/how-to-register-in-an-application. I still receive: 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 am using COMMUNITY LICENSE Could you please help? Thanks
