   1. EndNote X20 is found here – C:\Program Files (x86)\EndNote 20\
   2. EndNote X21 is found here – C:\Program Files (x86)\EndNote 21\
      
      
      
3. In the EndNote Configuration window:
   
   1. Select Configure EndNote components, then select Next.
      
      
      
   2. Check the Cite While You Write add-in for Microsoft Office checkbox, then select Next.
      
      
      
   3. You may receive a UAC prompt. Follow the Just-in-Time (JIT) Elevated Privileged Access instructions.
      
      
      
   4. Select Finish.
      
      
      
4. Open Word and verify that EndNote shows in the Ribbon.
