And you extracted all of the data from the .zip files prior to initializing the installation? From the sound of it, if you're starting the installation from the zipped folder itself, that's more than likely why it's not working at all - in cases where an installation relies on external data files that are included, they have to be uncompressed so that the data can be processed properly. Try unzipping them into a new folder location on your hard drive (somewhere that you'd remember to go back to once you finish to delete it later on, like your Desktop or a more frequently used folder), then start the installation process there.

But if that's what you were doing all along, ignore the first paragraph. You may have to try redownloading like MeerkatQueen suggested, it's possible that the files were corrupted due to not fully completing the download process for whatever reasons. ;-)
