Injection Troubles

Everytime I try to inject dll's into GTA5.EXE I get this error message.

System.AccessViolationException: Unable to allocate memory for the injection path.

Please help, I have tried to use multiple injectors, and none of them seem to work sadly, please help ASAP!

Use Extreme Injector 3.6.1, it's one of the best. Here is a picture of my setting (that works for me), try them out. If it doesn't work after all of that, you are either trying to inject an outdated, patched, or broken menu.
