Hello, I'm evaluating the usage of the Spire.PDF but when I process the file, it can only see this message:
"To view the full contents of this document, you need a later version of the PDF viewer. You can upgrade to the latest version of Adobe Reader from ...
For further support, go to ...l"
If I open the file in Adobe Reader, the contents (actually a form) is displayed correctly.
Is my PDF file incompatible with Spire.PDF?
