I am wondering if anyone can help me to figure out what is happening with the PDF viewer of EndNote.
I use EndNote 20.1 which suposed to allow me viewing the PDFs on the same window. However, for some reasons, the attached files are not detected by the EndNote, and as a result, I am unable to view pdfs on the same screen which is very inconvenient. I have created a new library, attached all the PDF articles again, but the error keeps ocrring and tells me that the references are “unfiled”.
I have attached a screenshot that can help you understanding what it looks like in my case. Please have look and any help is appreciated!
