You can set the license by following the steps below:
Once you purchase a full license from Dynamsoft, you can find your license information in the Customer Portal (License | Full License).
To activate the license, click "Activate".
On the next page, set an Alias for your license or leave the default Alias, choose where you want the license to be hosted ("Dynamsoft's License Server" or "My Self-Hosted License Server") and click the "Activate" button.
Alias is a way to identify the license. You can set a meaningful Alias to a license so that you can easily identify the purpose of the license.
In most cases, you should choose "Dynamsoft's License Server", choose "My Self-Hosted License Server" only when you have consulted us.
You might be prompted to add the new license to an existing project or create a new project for this license.
On the following popup window, click the "OK" button.
You will find that the License Key is listed on the license details page now.
You can copy the License Key and use it in your application.
If you have other new licenses, you can follow the same steps to activate them.
A license usually expires one year after it is activated. Do not activate the license until you actually need to use it.
If you have multiple projects which you want to manage the license usage separately, you can click the project name (found after "Linked Project Name") on the license details page to get to the configuration page. Read how to manage the project for more information.
Replace the trial license with the purchased license key:
