No driver found for virtual drive

[gnozal]

Thanks, but unfortunately it doesn't work.

Cannot install this hardware.

There was a problem installing this hardware :
PF3061B NFP980Q SCQI CdRom Device

An error occured during the installation of the device

Access is denied

How does one 'unlock' a drive ?

Try manually updating the driver and point it towards C:\Windows\inf\cdrom.inf

Using DT Lite 4.12.1 on Win XP sp2 (the same problem also happens with DT 3.47),
with admin rights (also tried with 'Run as' administrator).

Note : no internet access on this computer.

1. DT installation
After reboot, windows detects a new device and says 'access denied'.
DT installer does not complain.

2. Adding virtual drives
For each drive added, windows detects a new device and says 'no driver found'.
In the device manager, the virtual drives have an exclamation mark (!) and in the information box it says 'no driver found'.

Note that DT virtual mounted disks work despite this annoying error message.
How can I get rid of this message each time a vitual drive is added ?

(sorry for my bad english)
