To install Legends of Ancient Arabia (updated for 2025):

Download AncientArabia-2025.7z. In Windows 11, no special software is needed to open this file. In previous versions of Windows and maybe MacOS, go to 7-zip.org to download 7-zip.

Make sure Civilization 4 complete is installed. In the install location for Civ4 (e.g. Program Files (x86)/2K Games/Sid Meier's Civilization 4 Complete/, but your exact path is probably different), look for Warlords/, then look for Mods/. Put the Ancient Arabia/ folder in that Mods folder.

Now, start up Civ 4 Warlords, go to Advanced → Load a Mod → Ancient Arabia.

This will start up Legends of Ancient Arabia. To start out, start a single player game, choose the EZRLakmidCaulixtla map, and play the Lakmids at Settler difficulty. This will be a long but easy game, have fun!
