What did you download and what did you then do with it? If you downloaded the ISO you need to burn it to a CDROM (Nero File->Burn Image) and then insert it into your CD player and reboot your PC. Assuming you have the correct boot order (ie CD first) then it will boot from the CD and run Knoppix. You don't run this from within DOS/Windows.
