Template:InstallArxFatalis

First, install the original game from either the GOG.com, Steam, the Microsoft Store or the Bethesda Store or a CD.

If you installed Arx Fatalis from CD, you need to apply the 1.21 patch. If you installed the game from Steam, GOG or the Bethesda launcher, the 1.22 patch is already included when you download the game and you don't need to manually apply it.
