I have a PDF file I can open and see. The problem is when I try to open the same with A.PDF.PR 2.12 I get the following message: "This document was created with eBook Exchange(EBX_HANDLER) 64-bit security v.4 encryption handler. This protection method is not suported". A.PDF.PR 2.12 can only open 40-bit encryption keys. Is there another program that can do this for me? That can atually decrypt 64-bit v.4 encrypted PDF files?
