A unique license key string is generated for each purchase. In order to unlock the PDF Creator product you have to set the LicenseKey static property of the LicensingManager class with the license key string you have received after the product purchase before saving a PDF document.

The license key contains the information about the purchased product like the product version and license type and is uniquely associated with an order ID. More details about the license types and pricing can be found on the Buy Now page of our website.

Sample Code

Here is how you can set the License Key in code:

ExpertPdf.PdfCreator.LicensingManager.LicenseKey = "license key here";
