Hi,

The error message indicates that you might be directly adding DynamicPDF product serial number as license key to the application. Please login to our CustomerArea: https://www.dynamicpdf.com/customerarea and retrieve the license key for your product and then add this to the application.

If you continue facing an issue then please send over following information to [^a|mailto:support@dynamicpdf.com|opennewwindow|support@dynamicpdf.com^] so we can look into it further.

1.Exact watermark numbers[xx:xx:xx:xx] displayed on the output PDF or the output PDF having watermark on it.
2.DynamicPDF license key added to the application.
3.Exact version and build number of DynamicPDF Core Suite for .NET product used in your application. You can find this information by right clicking on the DynamicPDF Core Suite DLL file>>Properties>>Details tab>>Product version. Take a screenshot of Details tab and send it over to us.

Please do not share license key and product serial number details on forum.

Thanks,
ceTe Software Support Team
