I see you misspelled Windows.. Oh well, try to be more careful next time.
And about the problem.. either select search cd rom drive and have the disc in the drive, or browse the correct dir in the specify a location box.
The "specify a location" has to be where the driver's .inf file is, else Windows won't find it. (usually the search in cd-drive option is correct, as most driver cds have the infs in the root directory)
I'd suggest you get the newest reference drivers from the chip manufacturer's website anyways, those CDs that come with the cards are obsolete before the card hits the shelves.
And you're right, there are hundreds of Windows-specific forums out there, that could have helped you.
