Installation Steps
1. Create a Steam account if you don’t have one (visit [store.steampowered.com](https://store.steampowered.com)).
2. Install the Steam client from the official website and log in.
3. Purchase the game:
- Search for “Call of Duty: Modern Warfare” (NOT “Modern Warfare Remastered”). The product page should show the original 2007 release.
- Click “Add to Cart” and complete the purchase.
4. Download:
- Go to your Steam Library → find “Call of Duty: Modern Warfare” → click “Install”.
- Choose the install location and confirm. The download size is approximately 6–7 GB.
5. Wait for download & installation – Steam will automatically install the game once downloaded.
6. First launch:
- After installation, click “Play” in Steam.
- The game will present a launcher where you must enter your CD key (this is usually the same key Steam provides – it may be auto‑filled or you can copy it from Steam > Library > right‑click game > Manage > CD key).
- Activate the key (you may need to be online).
- Set graphics and audio options, then launch the campaign or arcade mode.
> Note: Older versions of Windows (XP/Vista) may require the latest DirectX 9.0c redistributable. If you get “d3dx9_???.dll” errors, install the [DirectX End‑User Runtime Web Installer](https://www.microsoft.com/en-us/download/details.aspx?id=35).
Common PC Installation Errors & Fixes
| Error | Cause | Solution |
|---|---|---|
| Disk Write Error | Corrupted download or insufficient permissions | Run Steam as administrator. Verify integrity of game files (Library > right‑click > Properties > Local Files > Verify Integrity of Game Files). |
| Missing d3dx9_34.dll | Outdated DirectX 9 | Install the DirectX redistributable linked above. |
| The game does not start / black screen | Fullscreen resolution mismatch or missing‑rendering drivers | Update graphics drivers. Launch the game in windowed mode by adding `-windowed` to launch options (Properties > General > Launch Options). |
| “Error Code: –1” or “Steam must be running” | Steam client not running or outdated | Restart Steam, ensure it’s updated. If using a cracked version, remove it – this guide only covers legitimate copies. |
| Multiplayer “Unable to connect to server” | Official game servers are offline | Only LAN or private community servers work. Use tools like “Call of Duty 4: Promod” or VPN LAN apps. |
Xbox (Xbox 360 / Xbox One / Xbox Series X|S) – Step-by-Step Installation
Requirements
- Digital: Xbox Live account (free for offline play). Storage: ~7 GB free space.
- Disc: Xbox 360 game disc; Xbox One/Series X|S can play it via backward compatibility if the disc is inserted (you must be online to download a compatibility patch).
Installation Steps (Digital)
1. On your console, sign into your Xbox Live account.
2. Go to the Microsoft Store (on Xbox 360 dashboard, go to “Games” > “Browse Games”; on Xbox One/Series, use the Store app).
3. Search for “Call of Duty: Modern Warfare” (the original – not “Modern Warfare Remastered”).
4. Purchase the game (or install if you own it).
5. Start the download. You can monitor progress in “My games & apps”.
6. Once downloaded, the game will install automatically. Launch from the dashboard.
> Note: If you already own the game digitally on Xbox 360, on Xbox One/Series you may need to go to “My games & apps” > “Full library” > “Ready to install” to find it.
Installation Steps (Disc)
1. Insert the Xbox 360 game disc into your console.
2. If you are using an Xbox One or Series X|S, the console will download a backward compatibility emulation patch (several hundred MB).
3. Wait for the download and installation to complete.
4. You may be prompted to install the game from the disc (on Xbox 360, disc installation is optional but recommended for faster loading).
Common Xbox Installation Errors & Fixes
| Error | Cause | Solution |
|---|---|---|
| “This game isn’t playable here” (Xbox One/Series) | The disc region does not match the console region, or backward compatibility patch failed | Ensure your console supports Xbox 360 games (series S does not have a disc drive, so digital only). Use a disc from the same region. If patch fails, try restarting the console and going offline then online again. |
| Download stuck at 0% | Server issues or full storage | Check storage space, restart console, cancel and retry download. |
| “The game took too long to start” | Corrupted local save or cached data | Clear the Xbox 360 cache: Settings > System > Storage > Clear system cache. On Xbox One/Series: Settings > Disc & Blu‑ray > Persistent storage > Clear. |
| No sound in game | Audio output settings | Go to Xbox audio settings and ensure the correct format (e.g., stereo uncompressed) is selected. |
PlayStation 3 – Step-by-Step Installation
Requirements
- PSN account (free to create). Storage: ~6 GB free space (game + install).
- Digital purchase: Must be done through the PlayStation Store (still accessible from the PS3 console, or via web browser at [store.playstation.com](https://store.playstation.com) using your PSN account).
> Warning: The PS3 online store is deprecated on the console, but purchases can still be made. Some regions may no longer sell the game digitally. If you cannot find it, a physical disc is your only option.
Installation Steps (Digital)
1. Turn on your PS3 and sign into your PSN account.
2. Go to the PlayStation Store (icon on XMB).
3. Search for “Call of Duty: Modern Warfare”.
4. Purchase the game (ensure your wallet has funds).
5. After purchase, go to the download list (Account Management > Transaction Management > Download List).
6. Select the game and start the download.
7. Once downloaded, the game will appear on the XMB and install automatically. Launch it.
Installation Steps (Disc)
1. Insert the PS3 game disc into the console.
2. The game may prompt you to install data to the hard drive (strongly recommended). Confirm.
3. Wait for installation to finish (a few minutes).
4. The game is now ready to play from the disc icon.
Common PS3 Installation Errors & Fixes
| Error | Cause | Solution |
|---|---|---|
| “An error occurred during the download. (8002AE23)” | Network error or corrupted download | Pause and resume the download, or delete and restart. Ensure the PS3 has a stable internet connection. |
| “The install cannot be completed. (8001003D)” | Corrupted game data or insufficient space | Delete any previous game data from Game Data Utility on XMB, free up space, and reinstall. |
| Disc not recognized | Dirty or damaged disc, or region mismatch | Clean the disc with a soft cloth. If the problem persists, the disc may be defective. PS3s are region‑free for games, so any region disc should work. |
| No sound or sound stuttering | Audio output settings | Go to Settings > Sound Settings and try changing the audio output (e.g., from Dolby Digital to Linear PCM). |
Post‑Installation Verification
After installing on any platform, run the following checks to ensure the game is fully functional:
1. Launch the game – It should start without crashes. On PC, the launcher may appear; on console, the game boots directly.
2. Start a new campaign – Play through the first mission (“F.N.G.” – the training level) to confirm controls and performance are normal.
3. Check for updates – On Xbox/PS3, the console may automatically download patches; on PC, Steam handles updates. Ensure you are on the latest official version.
4. Verify file integrity (PC only):
- In Steam, right‑click the game > Properties > Local Files > Verify Integrity of Game Files. Steam will replace any missing or corrupted files.
5. Test local multiplayer (console) or LAN mode (PC) if desired, to confirm network play works (official servers are down).
If any of these steps fail, refer to the common errors section above.
