version_info refers to the version of Python you are running (hence sys.version_info). Have you updated to PyPDF2? It seems that you are using the original pyPdf; that name is no longer used. Additionally, your file object (file(fileName, "r")) is not open in binary mode, which is likely the main cause of the problem (use "rb").
