Hi mingus123 ,
Please provide the exact dot version of the software & OS installed at your system .Also check whether is there any update available for the software after going through "help > check for updates "
Would like to know are these files are saved over server drive , if yes then first save them to local drive & then check for the same .
Also would request you please share your work flow as well.
You may also check with different user account with admin rights to replicate the issue.
This is the version of Acrobat I'm using. It is up-to-date. I'm running Windows 7. The files are on my local drive. My workflow is that I am...
1. Opening a PDF
2. Going to edit
3. Entering the password
4. Going to "add background"
5. Selecting "apply to multiple files"
6. Entering the password for each file in the queue
7. Clicking "ok"
That's when I get the above error.
Remove the security before you add the background.
