The link provided didn't work for me. I have Endnote X7.2.1 on my Mac OS X 10.9 but also I would like to use Endnote X7 on a Windows 7 machine. I have my library online too, I tried to create a new empty library in wondows and then to sync from there but it won't work. How can I safely and sucessfully make a copy of my library on mac to a windows machine? thanks for helping!
