What Paradox Launcher is

Paradox Launcher is a free launcher for games published by Paradox Interactive. It has downloads for Windows, Linux, and macOS, and lets users link Paradox and Steam accounts to access select games through Paradox. The launcher page also says owners of Crusader Kings III, Surviving Mars, or Stellaris purchased through the Paradox Store can download it and play. Paradox says the launcher or a game may automatically download and install updates, upgrades, and additional features. The company may require the launcher before a game can be played; without it, related services may not be available. Some services may require a Paradox Account. The launcher supports mods and playsets, with Paradox support guidance for cases where they do not appear. Antivirus or ransomware protection may prevent them from loading, and Paradox recommends adding the launcher and game executables to antivirus exceptions. For issues starting a Steam game, its guidance includes checking antivirus allowlists and quarantined files and keeping Steam and the game on the same partition. Paradox Interactive develops and publishes strategy and management games for PC and consoles.

Who it suits

It suits players of Paradox-published games who want to launch them on Windows, Linux, or macOS, and players using Steam or eligible Paradox Store purchases. Mod users may find its support guidance useful when mods or playsets fail to appear.

What it does well

Free to use, with downloads for Windows, Linux, and macOS.
Links Paradox and Steam accounts for access to select games.
Supports mods and playsets.
May automatically install launcher or game updates.

What to know first

Account linking provides access to select games, not a complete catalog on the launcher page.
Some services may require a Paradox Account.
Paradox may require the launcher before a game can be played.

Getting started

Open the Paradox Launcher page.
Download the version for Windows, Linux, or macOS.

Verdict

Look elsewhere if you need a launcher that works without installing Paradox Launcher for games that require it, or if you need a complete catalog from the account-linking page.
