I'm having trouble with scanned files produced in Pro 9.0 not being able to be opened by e-mail recipients. I'm sure it is a backwards compatibility issue with reader, but this wasn't an issue in earlier versions.
Any suggestions? Are there settings I'm missing?
Thanks
What is the version of your PDF file (File>Properties) ?
What is the version of Acrobat/Reader being used by the recepient who cannot open the file?
