Finally I have got the code to compile the ineptpdf v3 script file. If I use this sript for decrypt a PDF file with DRM protection I get an error during the process: "error decrypting book session key".
However if I use the ineptpdf v2 script I get a PDF file without DRM protection but with all pages blank. Adobe Acrobat Pro 9 can't open it, but if I use the Nitro PDF Pro 6 I can open the PDF file (with blank pages) and I can check that version is a PDF v1.4.
Is there any solution to solve the error message "error decrypting book session key"?
Where I can to get the file or code for ineptpdf v4?
