      Send a screenshot of your game directory and where you linked the launcher to

        I worked it out.

        The recent MW3 update changed the game from 32-bit to 64-bit, and Plutonium IW5 currently doesn’t work with the new 64-bit version.

        Luckily, on my system I found a copy of the old 32-bit files here:
        %LOCALAPPDATA%\Plutonium\game-files\iw5-legacy

        I pointed Plutonium at that folder instead, and it started working again.

        If you don’t have that folder, Plutonium staff have also posted instructions for downloading the older 32-bit IW5 files through the Steam console.

        Hope this helps anyone else who runs into it.
