Downloading Rpg Maker 2000 RTP 1.0

[xXNoZXx]

I'm having some problems with the Rpg Maker 2000 RTP 1.0. After I download it, I try to extract it (.zip folder) but then a dialog box pops up saying there's nothing to extract. I've tried downloading it several times now and it still comes up with the same result  Help, please? > <
