I can't find the .dll for both the WinRaR and 7 zip after I clicked on them. Is there a specific file that I need to look into or did I do something wrong?

Well I downloaded the t4m file and once it is done loading, I clicked on it. Then, it took me to some "ashampoo zip" site where they require a paid member ship to open. I am not sure if I am the only one with the problem because guides on youtube have this pop up.
