I have a user where he cannot open some PDF documents yet can open others. I have a different user with the same exact version of Acrobat and he can open all the same PDF documents that the first user cannot. I have uninstalled Acrobat on that problem machine and re-installed and still have the same problem. I looked on-line to see if there is a solution yet can't find any. Suggestions?

Productivity software is application software dedicated to producing information, such as documents, presentations, worksheets, databases, charts, graphs, digital paintings, electronic music and digital video. Most common programs and suites such as Microsoft Office and LibreOffice have their own topics. Office suites, which brought word processing, spreadsheet, and relational database programs to the desktop in the 1980s, are the core example of productivity software, but they can include communications software, personal information managers, groupware and log analysis software.

Optical character recognition (OCR) is the mechanical or electronic conversion of images of typed, handwritten or printed text into machine-encoded text. It is widely used as a form of data entry from printed paper data records, including passport documents, invoices, bank statements, computerized receipts, business cards, mail, printouts of static-data, or any suitable documentation. It is a common method of digitizing printed texts so that it can be electronically edited, searched, stored more compactly, displayed on-line, and used in machine processes such as machine translation, text-to-speech, key data and text mining. OCR is a field of research in pattern recognition, artificial intelligence and computer vision.
