Everything should be straight forward (do not mess around with Advanced settings unless you know what you are doing). Go into Settings and customise the settings to your liking. You can disable/enable which DLLs to inject so you can keep your favourite DLLs without needing to find them each time. You can also drag and drop them into the DLL list. Add the DLLs you want by clicking on the Add DLL button.
(Note) If you are injecting into Combat Arms, make sure to type in Engine.exe If you want to target a specific process or select by window name, use the Select button. Type in a process name into the box (including the extension). (optional) Click Settings and then Start in Secure Mode to avoid Anti-Cheat detection of the injector itself.
