Operating System: win 2k sp4
Burning Software: NTI v7
Anti-virus Software: NAV 2003
DAEMON Tools Version: 3.47

I tried to install SP4 but it kept complaining atapi.sys in use. Uninstalled DT v3.47 (this may have been upgraded without unmounting drives) but two virtual drives stubbornly appear in the CDROM hardware profile. Tried uninstalling these drives but they just keep coming back. I don't understand how these drive can exist without DT being installed.

Now DT will not install, says that something is wrong with the hardware.

Whats going on?
