The installation procedure is still the same, but in order to have an up-to-date geo-database MaxMind requires you to create a free account and generate a free license key. So, it’s MaxMind to blame for and not Pascal.
Also if you need automatic updates of the geo-database (Pascal removed this feature several versions ago due to legal complains) you might want to check-out the Lite version of the plugin at https://github.com/acidstout/iq-block-country-lite
It is actively maintained and based on Pascal’s version. The only differences are, that I removed the optional tracking feature and the Webence API, did some cleanup and added an option to enter your MaxMind license key in order to enable automatic updates of the geo-database.
