When trying to open a PDF generated from InDesign or Illustrator, Acrobat displays the following error message:
"Acrobat could not open '[name of file]' 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).
To create an Adobe PDF document, go to the source application. Then print the document to Adobe PDF."
Using Apple Preview, the error is, "Couldn't open the file. It may be corrupt or a file format that Preview doesn't recognize."
The file was created by selecting the option "Save as PDF" from the Mac OS Print dialog.
This workflow is not supported.
