W2K sp4 update

I am running W2K and trying to load SP4 update. I have shut down all? applications but during installation following error message appears "e:\winnt\system32\drivers\atapi.sys is open or being used by another application"
Does anyone know what this pertains to and what other application should be shut down

atapi.sys relates to your harddrive software driver, you don't say how large your harddrive is, but it's obviously partitioned and maybe on the large size. Try here and see if this is any help. click here
