Need Help With Converting nkit to iso

I've been trying to download wbfs's or just iso's directly for wii but it always just downloads the one that requires the nkit and partitions to use but whenever I try to download that stuff I get the same "file missing" error while downloading. I've looked for guides and downloaded nkit from other places but there's always a problem and I can't find a solution anywhere! Is there something I'm missing or a way to just get the iso's instead of going through all this?
