Spire PDF Pro License

[vincent.tudo]

Hi,

I've been using Spire PDF Pro v8.7.2 with .NET Core 3.1 to generate PDF for our system. Recently, we have just upgraded the system to use .NET 8 and upgraded Spire.PDF to v11.2.4, also renewed our license due to it has been expired. However, we're encountering a strange issue that sometimes the generated PDF have the evaluation warning in every page header.

Have been trying to load the license explicitly by using the solution as proposed in your document but the issue still persist

Code: Select all

Spire.Pdf.License.LicenseProvider.SetLicenseKey("your license key");

Could you please let me know if there is any problem with the license? Or anything that can help me to fix this issue?

Thanks.
