PDF Concatenation Error

Please find attached 2 pdf files. When I concate them resulting file is not been able to open.

Can you tell me what is wrong?

I am using following code.

Dim pdfEditor As New PdfFileEditor()
pdfEditor.Concatenate(“D:\file1.pdf”, “D:\file2.pdf”, “D:\merge.pdf”)

Could you please try to use the latest version at your end as well? If you still find the same issue then please share the following details: OS and .NET Framework version. We’ll further investigate this issue and guide you accordingly.
