How do i put a .dll file into a .rar file??

I have a VERY good hack. It's not mine, But i have the .dll file, but it needs a seperate injector.. Which i also have, But i dont have the .rar file with the injector in it, Only the saved .exe on my desktop... And for some reason it wont let me just add the .exe (injector) into the .rar file, with the working hack .dll
Any suggestions?? And dont give me answers that wont help, I'm not posting this hack for my own benefit -_-
It's the best one out right now though, At least public.

You need winrar, i assume you have that, ok after that right click on the file(s) you wish to add to the .rar , click the option that says add to archive, name the archive w/e u want as long as its simple. then it will make the .rar file for you, it will look like a stack of books.

After that, go to Virustotal upload the .rar file, then copy and paste the url on ur address bar into the thread your posting the hack on, also you might need a screen-shot of the hack in-game; Since you are not yet a trusted member. for further reference look at stickies in this section regarding the post of hacks.
