How to Install MCCC

Complete step-by-step guide for installing, updating, and troubleshooting MC Command Center on Windows and macOS.

Prerequisites

Before you begin, make sure you have:

  1. The Sims 4 installed and updated to the latest version
  2. Windows or macOS — MCCC does not work on consoles (PlayStation/Xbox)
  3. A file extraction tool — built into both Windows and macOS
  4. At least MCCC v2026.2.0 for the latest game patch (PC: 1.122.218.1030 / Mac: 1.122.218.1230)
Legacy Edition: If you're on The Sims 4 Legacy Edition (32-bit), the last compatible version is MCCC 6.6.0. The current version only works with the 64-bit edition.

1. Enable Mods in Game Settings

The Sims 4 has mods disabled by default. You need to enable them:

  1. Open The Sims 4
  2. Click the three dots menu (top right) > Game Options
  3. Go to the Other tab
  4. Check "Enable Custom Content and Mods"
  5. Check "Script Mods Allowed" — this is critical for MCCC
  6. Click Apply Changes
Important: Both checkboxes must be enabled. MCCC uses script files (.ts4script) which require the "Script Mods Allowed" option specifically. The game may reset these settings after major patches — always re-check after updates.

2. Locate Your Mods Folder

Find the Mods folder on your computer:

Windows:

Documents\Electronic Arts\The Sims 4\Mods

macOS:

~/Documents/Electronic Arts/The Sims 4/Mods

Quick Access: On Windows, press Win+R, type %userprofile%\Documents\Electronic Arts\The Sims 4\Mods and press Enter.

3. Create the MCCC Subfolder

Inside your Mods folder, create a new folder called MCCC.

Your folder structure should look like:

Documents/
  Electronic Arts/
    The Sims 4/
      Mods/
        MCCC/
          mc_cmd_center.ts4script
          mc_cmd_center.package
          mc_woohoo.ts4script
          ...other module files
Critical: The MCCC folder must be only one level deep inside Mods. Paths like Mods/Script Mods/MCCC/ or Mods/Mods/MCCC/ will NOT work. Script mods can only be one subfolder deep.

4. Download & Extract MCCC

Download the latest version from an official source:

After downloading:

  1. Windows: Right-click the ZIP file > Extract All
  2. macOS: Double-click the ZIP file to extract
  3. Move all .ts4script and .package files into your Mods/MCCC folder
Do not skip extraction! Placing the ZIP file directly in the Mods folder will not work. You must extract/unzip the files first. Each module comes as a separate ZIP file — extract them all.

5. Restart The Sims 4

Fully close The Sims 4 and relaunch it. Do not just return to the main menu — completely exit the game and start it fresh. The game loads mods during startup, so a full restart is required for new mods to take effect.

6. Verify Installation

Load any save file and check for these signs that MCCC is working:

  1. Welcome notification: You should see "Welcome to MC Command Center" in the top-right corner
  2. Computer menu: Click any computer in the game — you should see "MC Command Center" as a menu option
  3. Sim menu: Click on any sim — "MC Command Center" should appear in the pie menu
Not working? Check that both "Custom Content" and "Script Mods" are enabled in Game Options > Other. Also verify your folder structure is correct (only one subfolder deep).

How to Update MCCC

When a new version is released, follow these steps:

  1. Delete all old .ts4script and .package files from Mods/MCCC
  2. Keep the .cfg files — these store your settings:
    • mc_settings.cfg
    • mc_tuner.cfg
    • mc_dresser.cfg
  3. Download the latest version from official sources
  4. Extract and place new files into Mods/MCCC
  5. Restart The Sims 4 completely
Your custom settings are preserved in the .cfg files across updates. You only lose settings if you delete these files or if a major update changes the settings format (rare).

How to Uninstall MCCC

To completely remove MCCC:

  1. Close The Sims 4
  2. Delete the entire MCCC folder from your Mods directory
  3. Restart The Sims 4

Your saves will continue to work normally — you'll just lose the MCCC features. No permanent changes are made to your save files by MCCC.

Troubleshooting

MCCC doesn't appear in game menus

  • Verify "Script Mods Allowed" is enabled (Game Options > Other)
  • Check folder depth — MCCC must be at Mods/MCCC/, not deeper
  • Make sure you extracted the ZIP files (not just moved the ZIPs)
  • Restart the game fully (quit to desktop, not just main menu)

Antivirus blocks or deletes files

  • MCCC files are Python scripts, not executable programs
  • Add your Mods folder to your antivirus exclusion list
  • Re-download if files were quarantined

"Last Exception" notifications

  • These indicate a mod conflict or outdated mod — not necessarily MCCC
  • Update MCCC to the latest version matching your game patch
  • Check for conflicts with other mods by testing with only MCCC installed
  • Report persistent issues on the official Discord

Settings reset after game update

  • EA patches sometimes reset the "Script Mods" option — re-enable it
  • Your MCCC settings (.cfg files) should still be intact
