How can I tell what version of Acrobat or Reader was last used to save a PDF file? My users are using fillable forms from grants.gov. We want them to use Adobe Reader 8.1.3 to fill these forms, but some accidentally use the Pro version of Acrobat. They need this to make PDFs from Word & other apps, but Pro will corrupt the fillable forms.
When I open a saved form in Reader 8.1.3 and click File > Properties it says Acrobat 7.x even though I know it was saved with 8.1.3.
Is there a way to know which version number and type (Reader or Pro) last saved a PDF?
