For pre-installed versions, you do not need to install anything. Navigate to the game folder.

However, the review would be incomplete without mentioning that the "free" route comes at the cost of security, mod support, and multiplayer access. If you fall in love with the game (which you likely will), the legitimate version is the only way to truly experience everything this simulation masterpiece has to offer.

The phrase "All DLCs included" is a game-changer for new players. The base game covers a good chunk of Central Europe, but the DLC expansions (Going East, Scandinavia, Vive la France, Italia, Beyond the Baltic Sea, Road to the Black Sea, and Iberia) transform the map into a massive continent.

When looking for a "top" download, reliability and safety are paramount.
