Hi,
There is no option to detect the evaluation watermark on the output PDF.
We have an AddLicense method which returns a true value if the added license is valid. If you are adding license key through a config file then try reading it in the code (using ConfigurationManager) and adding it to the application using the AddLicense method.
This allows you to know whether the application is licensed correctly or not.
Thanks,
