    Anyway I have resolve the issue:
    To resolve this behavior, follow these steps:
    Start Registry Editor (Regedt32.exe).
    Locate the UpperFilters value under the following key in the registry:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
    On the Edit menu, click Delete, and then click OK.
    Locate the LowerFilters value under the same key in the registry:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
    On the Edit menu, click Delete, and then click OK.
    ---------------------------------------------------
    This was written to someone who had problems with it's real CD-romplayers, and not virtual, but concidering it worked for me, it should work for you too. Good luck.
    Reboot after editing the registry then my cdrom drive is back. And, no more problem to set drive letter with DT.
    Big Thanks !!! :-)

    Darn wtf i just ran into the same problem in Vista x64 Ultimate

    All i did was to disable the virtual drive for testing reasons by setting number of devices to 0 . Now i tried to turn them on
    again by setting number of device = 1 and it takes about 30
    seconds to complete the operation but does NOT assign any
    drive letter. Also it does not allow to set a new drive letter.

    Oh yes i just see that also my USB DVD Drive is gone. Great! I thought
    this crap was ironed out already.

    This rig was running perfectly until that moment.

    Default no virtual drive

    I appologize if this is already posted, but I looked and did not see a resolution to my problem.

    I just got a new laptop with vista home premium. I installed daemon tools lite with no problems, no errors.....

    The virtual drive is non-existant. The only dvd drive that shows up in device manager is the physical drive. I scan for changes and nothing. In computer manangement there is no drive.... I have tried changing the letter of the physical drive. and the recovery drive just to make sure there was no drive letter conflict.

    I disable User acct control to make sure it wasn't a security issue that way. still no go.

    What am I missing? I have a desktop machine with vista ultimate on it and had no issues installing it at all.

    Thanks for the help.

    well, I discovered last night after posting my question that the virtual drive is in the device manager, but it is under "other devices". When I check for drivers it says none are installed. So, I clicked on update drivers. I first tried search automattically for drivers..... and it found nothing. I then tried to update the driver by pointing it to the cdrom.inf file as described in this thread: No drive letter(s) assigned to the virtual drive(s), or virtual drive(s) disappear But it cannot find the driver file there.....

    I started thinking about this as I was typing this....... and went to my other vista machine and copied the cdrom.inf file from that pc to a folder on this laptop. Then updated the driver again on the laptop and it worked!

    thank you

    Did you try to right-click on the Dtools program and choose "Run as Administrator"? Unless you disabled UAC, all accounts are run as limited users, and the first run requires Administrator privileges.

    I just got it working using the drivers in WIndows\System32\drivers for Vista but you have to find a cdrom.inf and put it in their and make sure cdrom.sys is in there as well. Then go to Device manager if there's no drivers installed for the SCSI Virt drive which was my problem, it's under Other Devices in the list. Click it and update the drivers - browse to Windows\system32\drivers and install them from there. And then wait a few mins and the drive letter shows up auto.
