If you are encountering issues with your game launching, please try the following:
- Verify the integrity of your game files on Steam
- Ensure the C++ runtime is up to date, see below for details:
- For Company of Heroes 3, Company of Heroes 2, and Dawn of War 3 Steam will install the required runtimes; for your reference here are the files it would install:
- Dawn of War 2 – the C++ runtime installers can be found in the ‘install’ subdirectory of the game install
- Dawn of War 1 – the C++ runtime installer is included in the Steam installation
- Space Marine – the C++ runtime installers are located in the ‘redist’ subdirectory of the game install
- Ensure your Operating System is up to date
- Uninstall and reinstall the game
