  • Bug Compare function, The file ... is protected, error

    I am using PhantomPDF 8.2 on Windows 7. When I try View > Compare, and select a pdf file for 'initial document', I get the message, 'The 'file ... PDF" is protected. Please enter a Permission Password.' The problem is, the file is not protected and there is no password. This happens for any PDF I try to compare, either in the 'initial document' or 'changed document', whether on the Desktop or on a network drive. These files can all be opened without problem normally.

    Why? How can I fix this?

      I also get an error when trying to compare two files:

Name:	Screenshot 2021-10-12 134901.png

      (I do not get a popup asking for permission password).
      These existing files MUST remain unaltered, as they are already final released versions of different revisions.
      I wish it could make a new/temporary file showing the differences.
      I'm on Version:; Windows 10 Pro Version: 10.0.19043 Build 19043
