Remove DRM from expired PDF: Error: Cannot find decryption keyHi everyone,
I succeeded removing DRM from most PDF files, but failed with expired PDF files, the error is "Error: Cannot find decryption key". Open PDF with Acrobat Reader: You are not able to open this document. Please contact your subscription administrator if you believe this is an error. To find your administrator, log in to your subscription and access the Administrators box on your Home page. Any idea? Thank you. |

Re: Remove DRM from expired PDFI don't think it is possible to remove DRM from expired ebooks. Besides DRM removal tools are intended to be used with legally purchased not rented ebooks.
