Advanced PDF Password Recovery: Protection method is not supported

Asked By randysprang 1230 points N/A Posted on - 07/18/2011

Hi guys, I am at our office, my boss ask me to open a PDF file that is locked, I search on the internet for software that is capable of doing so, I installed Advanced PDF Password Recovery to open the locked file, an error message was displayed when I am about to open the file, it said 128-bit security v.4 encryption handler, this protection method is not supported.

 

This document was created with ‘Adobe LiveCyycle Policy

(Adobe.APS[adbe.pdrl.v0]) 128-bit security v.4’ encryption handler.

This protection method is not supported.

 

When I analyzed the error, I am wondering of the capabilities of this application, or does the file I open has an error, I am having a hard time isolating the problem, please comment on my issue, thanks.
