Call of Duty: Modern Warfare 3 Multiple Profiles

Modern Warfare 3 Multiple Profiles Launcher

I created this launcher to provide multiple profiles for the single player game of Call of Duty: Modern Warfare 3. This is similar to the loader I wrote for Modern Warfare 2 which you can find here. As there are multiple ways to acquire this game and install it, this may not work for everyone.


  1. Download the zip file here
  2. Extract the contents to the install directory for Modern Warfare 3
  3. Create a shortcut on your desktop for MW3 Loader.exe and use it instead of launching the game directly.
  4. When you click “Launch” and you’re asked to select a program or shortcut to run, navigate to the shortcut you would normally use to launch the single player game and select it. This will ensure that the game is run through Steam.
  5. If for some reason you need to re-select a program or shortcut to run, you can do this by resetting the Loader. To do this you need to delete the settings.xml file located in:
    (XP) C:\Documents and Settings\All Users\Application Data\MW3_Loader\
    (Vista) C:\Program Data\MW3_Loader\
    (Win7) C:\ProgramData\MW3_Loader\
  6. If you don’t already have the Microsoft .Net Framework 3.5 installed on your system, you will need to download it here

Here’s a picture of what the game directory should look like after you’ve extracted the file:

Note: This only works for the PC version of the game and as far as I know only changes your Single Player profile, which includes all game settings and saved games.

If you have any questions or comments please feel free to post them below. Feedback and praise is always welcome!

  8. Abraham says:

    Hello,my problem is that it says after i create and press launch that steam must be running first even if it’s running,anyone had this problem and how to fix it?

    • Mel says:

      Hey Abraham, what shortcut/program did you select the first time you clicked ‘Launch’? You need to select the desktop shortcut that you would usually use to run the game. If you’re not sure what you selected you can always clear the selected shortcut and re-select it by following step 5 in the above instructions. Good luck! Let me know if you need more help šŸ™‚

      • Abraham says:

        Wait,so I need to have SP/MP icons on desktop,MW3 Loader too,open mw3 loader and when a window open when i press launch,select the desktop mw3 icon or what?..If is that,doesnt work neither

        • Mel says:

          Yep, you need to select the MW3 SP shortcut from your desktop after clicking Launch in the Loader. If it still doesn’t work try just running the MW3 SP shortcut on your desktop and see if that works. If that still doesn’t work I’m not sure what else to suggest. Sorry man =\
