Unable to set new drive letter under Vista

[Kid Boo]

After Installing V4 he removed all virtual drives. And now i cannot create a new one, everytime i go set device parameters and set there W: , E: , always the error comes.

Might want to mention what the error message was, otherwise they won't be able to do more than guess at the problem.

It shouldn't be possible to enter the Set Device Parameters menu with zero virtual drives configured. Hmm.

The Thread name was " Unable to set a new driver letter" so this was the error.

I have Device 0 and Device 1 , but they have no letter . The Error "Unable to set a new driver letter" comes if i try to set a driver letter.
I dont know if Windows or Daemon Tools have a bug ; Virtual CD couldnt do new driver letter too.

I just dont know how to get this work

I have the same problem. Canґt add a letter to the D-tool.

BUT my original Cd\DVD driver is gone to after installing
D-Tools 4. Tryd to repare it , but nothing. I delated the
drivers and reinstalld them but no luck. I get an error kod
the kod is 31.

Why did you post the same message 4 times? Learn to use the button.

Goto Device Manager and oben CD/DBVD-Rom and install manually the Drivers from x:\Windows\inf and the problem should be solved with Drive letters.

Otherwise more Infos plz, PC Configuration eg which Windows etc.

I searched Drivers from Windows\inf but he dont found any Drivers .

I have Windows XP Service Pack 2 , Athlon XP 2800+, 1 GB RAM , Nvidia 6800 GT .

Its Annoying

Mystique's answer should fix that .... but for me, it couldnt find any relevant drivers in the system folders ....

I pointed to the XP CD, and it found the drivers there ... sorted !!

Sry 4 post twice but i found a answer at http://forum.daemon-tools.cc/f19/vir...e-manager-2609

Just install manual from c:\windos\service the cdrom.inf and cdrom.sys and its work

I have tried the solutions here (and in the other threads), but when I go to manually install drivers, it finds the driver to install, then just keeps claiming its installing it (i've let it sit for hours). When the computer is idle, 1 thread of services.exe (umpnpmgr.dll) shoots up to 100% cpu usage. If I try to manually install the drivers then a thread of mmc.exe does the same. Any ideas?

I have the same problem. I am running Windows Vista RC1 x64 and Daemon Tools 4.0.6 x64. When I try to set letter for my virtual drive, I get: "Unable to set new driver letter"
