Start the game like you would normally, for example directly through Steam or Origin For example: 'C:\Program Files (x86)\Steam\steamapps\common\Mass Effect\Binaries\' It is easy to install and use and does not require any external configuration.Įxtract the file dinput8.dll to your main game folder.
