make sure that you already leeched your desired dll for private use.
next, move these injector.exe and dll files to any other directory on your PC
example) move them from "desktop/" folder to "desktop/avahack/" folder.
remember that you will launch the hack successfully if you keep trying multiple times with proper dll and injector anyway.
this way is for you to shorten the time wasted to retry the whole process again and again.
