Adobe software cannot and will not help you take of a password if you don't know what it is. But perhaps we can help you find out how it got there, to avoid this in future?
How exactly did you make the PDF? What software was used to prepare it, and to make the PDF? What version of software? What system?
OK, I can understand that. I need to know how the password got created. I created the document in zipForm® Plus 1506.3, a software program that provides real estate contracts, disclosures & other forms. Their forms are licensed. I am a dues paying subscriber. I don't see anywhere that it talks about oermission passwords on the .pdfs it creates. I'm running Windows 8.1 Professional.
Thanks for your help.
Here's what I would do. Make a new PDF with your zipform software. Immediately open it in Acrobat and check File > Properties under Permission to see if there is a password. That will tell you whether it is being put on at the time it is made.
Now, do you have Acrobat Pro, Acrobat Standard, Acrobat Reader, or Adobe Reader?
Aha! This is deliberate.
