Ok, so I feel really stupid right now... When you download a package for the sims 2, like hair or something, what do you do with it?
If u have it as a packege just press on it and it`ll install everything itself and if it`s a zip u`re to extract it into the Downloads folder.... I suppose it was your question
Also, make sure its not a folder or a folder w/ zip, make sure you just see the thing thats sorta white-ish and if you put the mouse cursor over it (not clicking it), it will say: TYPE: Package file SIZE: (however big it is, example, 606 KB)
