I am trying to work on a bid for a builder and the PDF sent to me claims to be password protected. Problem is, its not. At least not according to the builder and every other trade working on this mansion of a house. He uses the free version and opens it just fine every time. I pay for Acrobat PRO DC and am the only one having issues with the prints. I have the prints but will not upload them to the community because I can't read them so I have no idea if there is sensitive information I don't want to share. Any suggestions?
So the password prompt appears when you try to open the file? Can you post a screenshot of that window, at least?
I don't have to enter a password just to open the file, I can open the file without issues. The prints are encrypted so I can't take any measurements because that is considered editing and the PDF is secured. Funny thing is is that I have the option to add a password and protect the document so how is it already password protected? I've tried all the obvious things, including uninstalling the programs, and nothing is working.
It looks like the directory that contains the PDFs that asks for a password, not the PDF document itself.
You will not be able to add a password to a file that's already protected, if you don't know the password for it.
How did you arrive to that dialog, and what happens when you click on "Protect Now"? My guess is it's just an ad for this feature. It won't actually work on this specific file.
Looks pretty definite that it has a password. Please open the file and go to File > Properties then click the Security tab; please post a screen shot of the security info shown.
"My guess is it's just an ad for this feature"
Yes, this is an OneDrive ad.
(But not really an ad since this feature is included in the price)
