It's in a .zip format, probably because it has fonts in it. Right click and Save S to you Winamp skins folder. You should then be able to select it from Winamp's normal controls.

That should be:

"...Save as to your Winamp..."

Just put the whole zip file in your program files/winamp/skins directory, right click on the titlebar of winamp and select 'skins'...'Sputnik' will then be there...
