How to discover by which method a given Reader extended file received the extension of rights: by LiveCycle Reader Extensions or by Acrobat?

How to discover by which method a given Reader extended file received the extension of rights: by LiveCycle Reader Extensions or by Acrobat? I see some files have Signing Authority "ARE Acrobat Product v8.0 P23 0002337." Does this mean that the Reader Extensions were received by Acrobat, but not by LiveCycle Reader Extensions?

Yes. If Reader Extensions is used, it will say something like "ARE Production v6.1 P16 ID9416"

Thank you for a quick answer. But my question is how can we reveal the method used to enable reader extension. There are two methods to enable reader extension: by Acrobat 8 or later and by LiveCycle Reader Extensions. Does Signing Authority indicate the method by which reader extensions were enabled? For example, does Signing Authority "ARE Acrobat Product v8.0 P23 0002337" always indicates that reader extension were enabled by Acrobat?

That has been my experience. If the signing authority includes the string "Acrobat", the document was Reader-enabled with Acrobat.

Thank you so much, George for an excellent explanation!

"ARE Acrobat Product v8.0 P23 0002337" enabled by Acrobat

"ARE Production v6.1 P16 ID9416" enabled by LiveCycle Reader Extensions.

Is it possible to detect whether the file was reader enabled by Acrobat DC or by earlier version?
