Various websites, youtube videos, and blogs have talked about and suggested installing various add-on or installation "wizards". This is not a good idea, and doing so can cause more issues than it fixes. These tool likely started with good intentions, but many of the configurations it sets or changes will break or crash certain XBMC/Kodi setups.
Installing this so called 'wizard' may overwrite many configuration files without having an option to restore them.
