If you are asked for a product key, you have tried to install EndNote on a Windows device without first extracting/unzipping the downloaded file.
To extract the file, navigate to the zipped folder ENX8_WIN.zip. Right click on the folder and click Extract All.
Open the extracted (unzipped) folder. It will contain both a .msi installation file and a .dat license file. You will not be asked for a product key when you then run the installation file. After downloading EndNote, you may delete both the zipped and unzipped folders.
