You’re most probably reading this article because Kodi is showing you the “For security, installation of add-ons from unknown sources is disabled message. This happens when you try to install an addon that comes as a ZIP file, which means you’ve downloaded it from the Internet. However, there’s no need to worry - as we’ll show you how to enable unknown sources on Kodi and install any addon out there.

Before we dive deeper, here’s some handy background information. Back in 2019, Kodi’s developers started warning against installing third-party repositories, primarily due to malware concerns.

As you’re about to see, this process is incredibly simple and takes only a few moments of your time. And we’re going to show you how this is done on Kodi (applies to all Kodi versions).
