How to enable Campus GEO IP after install the plugin in matomo

I am using Matomo on premise. I am getting all the data that I want except geo location of the user. I am trying to use the Campus Geo IP plugin that is available in the marketplace, but even after installing the plugin, it says “not installed”, I have populated one(location table) of the two tables created by this plugin and have also deactivated and reactivated the plugin, but it still says “not installed”.
Please help me.
thank you.
