We are using ASPOSE.Total product to merge 2 pdf files using the concatenate method.
When we try to open the merged output pdf, Acrobat reader shows a dialog saying the file is corrupted.
On debugging this, i found that concatenate call is returning false but there are no errors or exceptions.
the merged pdf file version is 1.4 created with acrobat 5.x
Is this a known issue? Are there any suggestions on what is causing this issue and how this can be fixed?
I appreciate a quick response to this as we have customers waiting for a fix.
Update: I downloaded latest version of PDF Kit dll. I am now getting an InvalidCastException:
Unable to cast object of type 'xeb116a323308e2f7.xae94bcfc1c7ddd9a' to type 'xeb116a323308e2f7.x0b25947bdf0fba40'
I am attaching the PDF file that is causing this error.
