Can you try to disable UAC and see if it helps? You can enable it after though.
Just tried after desactivating it, but same problem.
Something i didn't said : after closing the pop-up saying "canno't inject code...." i have a microsoft .net framework error:
System.NullReferenceException: La référence d'objet n'est pas définie à une instance d'un objet.
à StarForge_CH.CHMonoCollector.Mono_FindClass(String namespaceS, String classname)
à StarForge_CH.CHMonoCollector.ReturnAddi(String className, String Methodname)
à StarForge_CH.Form1.ActivateTrainer()
à StarForge_CH.Form1.tHotkeys_Tick(Object sender, EventArgs e)
à System.Windows.Forms.Timer.TimerNativeWindow.WndProc(Message& m)
à System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)
I don't know if it helps.
