Try using the PerX injector, my favourite one atm, it's very easy to use. Just google it and download from there, should be easy to find. Just fill in what to inject with Engine.exe and How to inject with automatically. Click on add to injection list, and open the dll. for the hack. Make sure your anti virus scanner is off, I'd prefer turning it off with the option until system restart, so when you restart your anti virus will work again. Hope I helped!
