EndNote is asking me for a product key
Uninstall EndNote from your computer (Windows) or move EndNote to the trash (Mac). Close all your browsers. Open a new browser window (using a program other than Safari) and go to http://www.westernu.edu/library/library-electronic-resources/library-endnote/ and download the program again. If you have already downloaded EndNote twice, contact firstname.lastname@example.org to have your download count reset.
