Error opening pdf from email


 Respondents are getting an error message “Adobe Acrobat Reader could not open ‘certificate.pdf’ because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn’t correctly decoded).”

A custom script was used to deliver a certificate upon completion.  My investigation of Acrobat shows that the 10.1.5 and 11.0.01 updates improve security by enforcing stricter parsing of the PDF-header. The product now refuses to open the small fraction of PDFs that do not correctly start with the ‘%PDF-‘ header and the error appears.

Any help on the custom scripting for emailing a certificate?

      Hi Ann,

      I have flagged your posting for the attention of SurveyGizmo Support.

      Before i did this I tested a survey that we used last month to produce a certificate.   This survey worked with no problem last month, but we now getting the same error message that you reported.
