EndNote is asking you for a product key code because the files were not properly moved to your desktop prior to the installation. 

Make sure you follow Step 2 of the installation instructions: 

  • For Mac: Save the EndNoteX9SiteInstaller.dmg file onto your desktop. Then, double-click EndNoteX9SiteInstaller.dmg to start the installation process.  
  • For PC, save both files  (ENX9Inst.msi and License.dat) from the zipped folder onto your desktop. Then, double-click ENX9Inst.msi to start the installation process.
