Hi again,
I'm utterly confused as to what you are trying to do. Are you downloading VSTs linked from the VST thread?
If so, all you need to do is to unzip them into a folder (most people use a folder named "VST plugins") and tell Reaper in the preferences menu where you put them.
They can then be loaded onto tracks by pressing the FX button on the track you want them on.
This thread covers it too ..

Or are you trying to do something else?
