Thank you for the link to the clear instructions for Windows 10 and Word 2016.
I discovered that I cannot “Add” EndNote Cite While You Write because the location for the file “EndNote Cwyw.dll” is hidden in “Program Files (x86)\EndNote X4\ EndNote.exe”
In both my locations for “Common Files” there is no “ResearchSoft\ …”
I did for EndNote the “repair.” The EndNote software seems fine. I just can’t do the Add-in to get Cite WhileYou Write, which is so useful.
Is there anything else I can do?
