Kodi 18 Leia,17.6 has changed from the old interface to a fresh new look. It also has changed some options including now needing to Enable Unknown Sources to install add-ons.
- Open Kodi
- Select SYSTEM
Add-ons will now be able to be installed. To go back to the main menu right click a empty space on the screen, or click the top left Settings / System.
