Download and install the EA App. The launcher requires the EA App because The Sims 4 uses EA services even when installed through Steam.

Setup Guide — Getting Started with the Sims 4 DLC Launcher
Follow these quick steps to install the launcher, point it at your Sims 4 folder, and get every pack ready in minutes.
Install The Sims 4 base game normally. The launcher works whether you installed the game through Steam or the EA App.
- Steam path example: Steam\steamapps\common\The Sims 4
- EA App path example: EA Games\The Sims 4
Download the Sims 4 DLC Launcher from the Download page, then run it.
When the launcher starts, it automatically tries to find your Sims 4 installation folder. If it cannot detect the folder, it will ask you to choose the location manually.
Go to Tools, then click Install. The DLC Unlocker is already included and installs automatically — no extra setup needed.
Go to the Packs tab. Every pack is available directly inside the launcher. Click Download next to any pack you want, and the launcher handles everything automatically.
Once your packs are installed, simply launch The Sims 4 from Steam or EA App as usual.
