I am attempting to install XP SP2 on a pc but I get an error that the atapi.sys file is in use. I've found articles that say to disable Daemon Tools or Alcohol however, neither is loaded on this pc. Does anyone have any suggestions? Any help would be greatly appreciated!

Are you using any other CD Emulators like Astroburn or AnyDVD or other applications that create virtual hard drives on the system? Both of them are similar to Daemon Tools and Alcohol.

Atapi.sys is currently in use...Warning Message
Setup cannot copy the file Atapi.sys

The error message indicate on missing RAID adapter drivers or incompatible RAID drivers in the system.

atapi.sys is already in use try to close it message during Windows XP SP2 instillation

It's also possible the atapi.sys file is corrupted/infected. Look for a clean copy in the C:\Windows\ServicePackFiles\i386" or C:\Windows\$NtServicePackUninstall$\ folders, and copy it into the C:\Windows\system32\drivers\ folder so it overwrites the one that is located there.

To assist you with finding another copy, please download SystemLook from one of the links below and save it to your Desktop.

  • Click the Look button to start the scan.
  • When finished, a Notepad window will open SystemLook.txt with the results of the search and all locations where copies of that file can be found.
