I get this error message when i try to download using vortex. This file does not have an app associated with it for performing this action. Please install an app or, if one is already installed, create an association in the default apps settings page. Why is this happening? I also noticed that not all mods can be downloaded to vortex so what am i supposed to do? Why are these mods all over the place as far as getting them downloaded and usable?
