Unlocker.exe, google it. Unlock windows-system32-drivers-atapi.sys and click “retry”.

I forgot!
If you didint have WinXP w/ SP1 CD then I belive you will find atapi.sys in CDDrive:I386driver.cab

My sp2 installation said that it can not find file atapi.sys and not that is used by another program and therefor locked.
If I tried to open file for reading in any program I got error that file doesnt exist.
So I renamed atapi.sys to atapi.sys.old and I copyed from WinXP w/ SP1 CD from CDDrive:I386sp1.cabatapi.sys to windowssystem32drivers
This file was exact same size as old one in drivers directory. Well I clicked retry and it worked. Before renaming the non exsisting one I tried to copy atapi.sys to another directory but sp2 installer wasnt pleased so that didnt work.
Anyway this is far more simple solution and you dont have to cancel install of sp2 or uninstall anything

Valeri is right,
Alcohol 120% locks the atapi.sys file from use.
Uninstall Alcohol 120% and install SP2… things go fine.

If you have Alcohol => remove it .
and retry.
that’s it

I just renamed the atapi.sys file to atapibak.sys and a new atapi.sys, which was unlock and could be accessed, was instantly created by the system. Hope that helps.
