windows 7 ultimate (64 bit) black platinum edition download

ihave downloaded realtek hd audio driver through softonic downloader.While installing,the accept botton of the license agreement does not working. i have tried the tab+enter key. it still does not working.my pc is compaq b940 with windows 8.

after installing a new hard drive and downloading windows 7 i had the same problem with my dell. i had to go under device manager and since there were no drivers listed under sound i located under the unknown category. there was an unknown audio driver there so i double clicked it and updated the driver. now everything works perfectly
