Third party plugins and effects

How do I install 3rd party plug in effects into cubase element 7? I thought maybe when I downloaded them it would automatically recognize them but I thought wrong apparently lol PLEASE HELP!! LOL

Go into Cubase and under Devices tab, go to Plug-in Information. Go to “Plug-In Paths” and add the path where the 3rd party plug-in installer placed the .dll file. Then restart Cubase.
