I'm trying to install vista home premium on my pc. I get to 100% on the "expanding files" part of the installation, and this stupid f#&@ing error message pops up and says error code 0x80070570 windows is missing some file or something:upset:. This isn't a pirated copy, it isn't scratched, my hdd is fine, and my dvd drive is fine as well. PLEASE HELP ME!
