i'm trying to install service pack 1 (one) on this new install of windows. during the performing inventory phase, i get an error that reads: "The file C:\windows\system32\drivers\atapi.sys is open or in use by another application. please close all windows....yada yada" thing is this, i have no other windows open but the windows update IE page. if i try to close that page, it'll cancel the update. anyone else here have a similar problem in the past? all help is appreciated. -thank you.
