Normally the default setting is that Power-user should load automatically when you open PowerPoint / Excel / Word.


However sometimes, it can happen that Office will not automatically load the add-in, forcing the user to manually load it every time the application is opened.


To fix this, follow the steps below:

  • Click the Windows Start menu
  • Click "Run"
  • Type "regedit" to access the registry, and the "OK"

  • In the left menu, browse to HKEY_CURRENT_USER/SOFTWARE/Microsoft/Office/PowerPoint/Addins/PowerUser 

add-on load behavior in the registry

  • On the right, double-click "Load Behavior
  • Change the value to "3", which means Load at startup
  • Now restart PowerPoint / Excel / Word and the add-in should automatically load in the application.
