Evaluation Only Message (PDF)


The license we have for Aspose.Pdf.Kit.dll keeps reverting to evaluation mode and shows the “Evaluation Only” message n the resulting PDFs.

Within one week of publishing the licensed assembly, the message has returned. Our license, if I’m not mistaken is good for one year. And that’s not all, this message reoccurs every 25-30 days or so.

What causes this? How can we make the license stick?


Please note, you need to apply license once per application or process for each Aspose library by adding a couple of lines of code. You will not see this evaluation watermark when the license is applied properly to Aspose API. The Aspose license may not be applied at some stage during the execution of the application, so kindly apply license in some common area of the application, e.g. application start event.

However, if this does not help, then kindly share complete details of the use case, including source documents, code, Aspose.Pdf.Kit API version and license expiry date. We will investigate and share our findings with you.
