Aspose.PDF for .NET "license not valid for this product"

Aspose.PDF Product Family
1

Using Aspose.PDF for .NET 18.3.0 with a temporary license I received today. When calling the line:

license.SetLicense("Aspose.PDFfor.NET.lic");

it is giving me {“The license is not valid for this product.”} exception.

Pretty sure I selected the correct product when I requested the license. Thanks.

It is happening because the older versions of the API does not support SHA256 hash algorithm used in new licenses. Please use the latest available version of the API and if issue still persists, please let us know.

Thank you. I updated to 23.6.0 and it is loading the license now.

I am doing all of this to evaluate your product for updating an XFA Dynamic PDF form. With the license it seems to update the XFA field value (which it wasn’t doing before - it would just show null). But when I save the file it doesn’t have the value. Any help you can throw my way would be greatly appreciated. If I need to create a new forum entry just let me know.

Here is the code I’m using:

        Aspose.Pdf.License license = new Aspose.Pdf.License();
        license.SetLicense("Aspose.PDFfor.NET.lic");

        string inputFile = "C:\\TestConsoleApp\\PDFForm.pdf";
        string outputFile = "C:\\TestConsoleApp\\PDFFormEdited.pdf";

        Aspose.Pdf.Document doc = new Aspose.Pdf.Document(inputFile);
        string[] names = doc.Form.XFA.FieldNames;

        doc.Form.XFA[names[4]] = "Test Name";  //From
doc.Save(outputFile);
