I have a LENOVO FLEX 14, I've been playing minecraft for years but I've really been wanting to use mods, when I went to the minecraft forge website and tried installing the installer, a pop up came up and explained "This file does not have an app associated with it for preforming this action. please install an app or, if one is already installed, create an association in the Default Apps Settings page."
What does this mean and how do I work past it? I really want to use mods that are safe for my laptop. Help me?
