Paradox Launcher

What Paradox Launcher is

Paradox Launcher is a free launcher for games from Paradox Interactive, available for Windows, Linux, and macOS. Users can link Paradox and Steam accounts to access select games through Paradox. Owners of Crusader Kings III, Surviving Mars, or Stellaris purchased through the Paradox Store can download the launcher and play. The launcher or a game may automatically download and install updates, upgrades, and additional features. Paradox may require users to install and use the launcher before playing a game; without it, services may be unavailable. Some services may also require a Paradox Account. The launcher supports mods and playsets, and Paradox support provides troubleshooting guidance for cases where they do not appear. Antivirus or ransomware protection may block them from loading, and Paradox recommends adding launcher and game executables to antivirus exceptions. For Steam launch issues, its guidance includes checking allowlists and quarantined files and keeping Steam and the game on the same partition. Paradox Interactive is headquartered in Södermalm, Stockholm, and was founded in 1999.
