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

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 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"

Guys after installing 'DAEMON Tools 4.0.8 X86' on 'Windows Vista RTM' you need go to 'Device Manager' and update the device driver for the 'SCSI CDrom Drive'. The driver you need can be found in C:\Windows\System32\drivers\cdrom.sys. This works and I am using it without any problems.

Hey, had the same problem with the drive letters too (Windows XP), looked it up on google and found a solution for it. Don't know if you still need it, but it worked really great for me, so here it is.
-----------------------------------------------------
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.

THANK YOU very much abdulhakim01!
I had the same problem: i installed Daemon Tools 4.0.8 x86 on Vista RTM (6.0) x86, and I could not set the drive letter. Also, after installing DT, the dvd-rom letter did dissapear, but came back after 1st restart (I have asus dvd-rom and pioneer dvd-rw), but still no drive letter for DT virtual drive. After updating the device driver for scsi cdrom drive from device manager everything works just perfect! :D
Thanks again for your post, I was lost without Daemon Tools!

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.
Hi
my original question written for another forum before I discovered these forums is posted in quotes below. Also quoted above is what is said to be the solution, however I cannot carry all that out. I can find DVD/CD-ROM inside device manager where it has a good driver which makes it work for other purposes than "Daemon tools" . That installing it manually stuff doesn't make sense to me. How do you install it manually? Any answer to this question or my question as originally written below would be greatly greatly appreciated!

"Daemon tools" drive letter configuration problem?
Hi
on another thread somebody recommended to me to use this software, which is free for noncommercial use, called "Daemon tools." Having downloaded it and looked it over it seems like it should be great software if only I could get it configured. The software is said to have the capability of letting you make a backup copy of your DVDs in spite of the fact that DVDs are usually copy protected in a way which will not permit you to make backup copies.
My configuration problem with my copy of "Daemon tools" is I cannot configure it to recognize my DVD drive which is presently designated drive letter E on my computer. I have tried doing what "Daemon tools" recommends to change drive letters by going to "set device parameters" on one of the "Daemon tools" menu's. This yields a dialog box which only gives me the possibilities of changing the drive letter to F through Z but not E. I have tried reinstalling "Daemon tools" which did not alleviate this problem. I have also tryed to chang the designation of my drive letter in Windows XP however I do not know how to log in to my computer as an administrator. I stopped logging in to my computer almost as soon as I bought it and no longer know how to log into it as an administrator if ever I could. So I would really appreciate it if someone here could tell me how to fix my dilemma and get "Daemon tools" to work successfully with my computer.
I would consider using an alternative program that does the same thing as "Daemon tools", however free use is a very attractive price. So please tell me if there is an alterative programs someone here has used that works just as well or nearly as well.
Very sincerely

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.

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.

DT Lite 4.12 with SPTD 1.55? Also is a drive letter assigned to virtual drive?

acerhigh
28.01.2008, 12:50
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: http://forum.daemon-tools.cc/f26/no-drive-letter-s-assigned-virtual-drive-s-virtual-drive-s-disappear-3701/ 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.

I had same problem as described by several people above :D and was (as you can imagine) pretty annoyed. And after some struggelin i might have found an awnser everybody can use :)

(You don't need to uninstall deamon tools)
First go to the normal download site of daemon tools
Disk-Tools.com - Published Software Download (http://disk-tools.com/download/daemon+sptd+md5sum)
now comes the important part.
download the SPTD at the bottom of the site. (make sure you get the right version for your 32 or 63 bit system)
click on the SPTD file to open it...
Seeing that you all had daemon tools installed there will be 3 options you can click on.
I believe they are. Update, Uninstall and Cancel.
Click on Uninstall
Restart system.
Then click on the SPTD file again where you now have the options Install or Cancel
Install and then restart again.
Start daemon tools and now you probably have disk letters again
(looking at that the SPTD install is included in the daemon tools install file you can also uninstall the SPTD and after that deamon tools reboot and then just install deamon tools normally, this should work as well ;))
hope this helps some people (A) it did for me :D

You need to copy and paste the *.inf and *.PNF files from this folder:

C:\Windows\System32\DriverStore\FileRepository\cdr om.inf_b2045cb8
AND THIS FOLDER:

C:\Windows\System32\DriverStore\FileRepository\msh dc.inf_1d87dda2
to C:\Windows\inf

the *.sys files in those folders may be required to be copied and pasted into \System32\Drivers if not already there.

Now you need to go to device manager and right-click on the not working virtual driver which is probably now under other devices. Select to update the driver and now point to C:\windows\inf
should work fine now!

Hi, I've tried everything I have seen in this thread and I cannot get it to work. Whenever I try to update the drivers I get an error message saying it failed to install the driver (CD-ROM), the message under that is "Access is denied."

Any help would be appreciated.

Actually, I solved my problem. It wasn't related to a daemon-tools issue. But, in case anyone else has this problem at some point, here is the solution (I have no idea what caused it).

The problem was that I was no authorized access to the files the system needed to install the driver. So, to fix the problem I went into my registry (regedit) and gave myself Full access to everything in the Local Machine folder. This did not solve the problem. It might not even be necessary to do this.

Earlier I had come across a reg file that adds a little option in your right-click menu to take ownership of folders and files, found here Take Ownership of file - Vista Forums (http://www.vistax64.com/tutorials/67717-take-ownership-file.html). Using this I took ownership of the following folders:
windows/inf
windows/system32/drivers

and then the next time I tried to install the driver for the virtual drive it was successful. I don't know what caused this to happen, but if anyone else experiences something similar, hopefully this post saves you the 4 hours it took me. =)

I had the "no driveletter - can't change drive letter" issue.

However my cd/dvd-player was visible in Device Manager but they had a yellow "!". The Device driver could not be loaded.

I used this guide -> PC Hell: How to Fix Error Code 39 with DVD or CD-ROM drive in Windows XP/Vista (http://www.pchell.com/hardware/cd_drive_error_code_39.shtml)

Very easy and after the reboot, I had access to change the drive letters and everything is working again!

Hello together
I have a problem that could be related to this:
under vista 32 i can change the drive letter without problems and while the sessions lasts, everything is fine. But after a restart the letter is again the first free letter (e.g. D:).
This is also happens when i close Daemon Tools Lite Tray Icon, starts it as Administrator and change the letter in this way. After a reboot, the letter changed again.
Could anyone help?
Thank you
steven

the problem is the same as in this thread, i think:

After trying for at least one month, I am about to take a decision to give my laptop for HP service to replace my burner.
But meanwhile, when I want to read an ISO file, this daemon tool problem - 'unable to set drive letter' started pestering me. So I tried all the previous solutions given above, but in vain. Finally yours did the magic not only with 'Daemon Tools', but also with my burner.

Million thanks to you!

Your CD drive or DVD drive is missing or is not recognized by Windows or other programs (http://support.microsoft.com/kb/314060/EN-US/)

The fix....


It works on all versions of windows having this problem.

They say any software that can burn a cd/dvd or manage drm or video/music can trigger this problem upon install.

Common triggers are installing winamp or nero or even d-tools.

This fix worked on all my systems, and it is also what you need to use for the HP-Optical problem as well as the sony vaio one.

Aparently for some reason their OEM software triggers it every time you do a update.

Have fun.

quote of copytrooper:
"Check in device manager if any drivers are installed for the virtual devices. There should be cdrom.sys, storprop.dll and redbook.sys.
If no drivers are installed, click on install drivers and point to cdrom.inf - or mshdc.inf (for vIDE) - supplied by OS (in hidden Windows\Inf folder).
If all mentioned drivers are installed, but also some additional filter drivers check this thread, too:
My real cdrom/dvdrom drives are missing - THE DAEMON TOOLS FORUM (http://www.daemon-tools.cc/dtcc/showthread.php?t=440)
Also check if you've a file infcache.1 in Windows\Inf folder, (re-)move it, then try again."

in my Vista x64 the VIDE drive only driver is cdrom.sys and nothing else. If i manually update it with mshdc.inf it doesnt change anything.

My Virtual Drives get unusable after almost every suspend to ram or suspend to disk sleep mode and i cannot assign drive letters to them any longer until reboot.

This problem is persistant for over a year over VARIOUS OS installations, so its NOT my system.

I have not installed or used any program that changes access rights to hives or any hide programs previous to the problem occured. I also have not installed any Burning Software that uses own drivers such as NERO. I also dont even have a hardware Optical drive. I only have a USB DVD that i have not connected.

well i dont blame DT for all this...after all the 680I nforce is a retarded chipset with retarded drivers, some many weird shit happens with it...

kicked out all nforce drivers and using the ones windows vista (sp2), installs by itself now... majority of problems gone...(just wait for them to resurface again for no obvious reason ^^)

You need to copy and paste the *.inf and *.PNF files from this folder:

C:\Windows\System32\DriverStore\FileRepository\cdr om.inf_b2045cb8
AND THIS FOLDER:

C:\Windows\System32\DriverStore\FileRepository\msh dc.inf_1d87dda2
to C:\Windows\inf

the *.sys files in those folders may be required to be copied and pasted into \System32\Drivers if not already there.

Now you need to go to device manager and right-click on the not working virtual driver which is probably now under other devices. Select to update the driver and now point to C:\windows\inf
should work fine now!


This works fine!! thank you! :)

hi, when im installing daemon tools, i get a message that the device drivers need to be updated, i tried to update it online (didnt work), searched the daemon tools website for drivers (not there), and tried several folders on my hd (didnt work either).
as long as this drivers are not installed, it seems impossible to create an (working) virtual drive.
Atm i have windows vista again, i didnt have the problem with windows 7. i also had win vista for a while before 7, back then DT worked fine with vista..

ive tried different versions of DT, but they all have the same error.

does someone know, where to get the update for DTsoft device drivers??

the error is:

D-Tools 4. Tryd to repare it , but nothing. I delated the
drivers and reinstalld them but no luck. I get an error kod

Hallo sarah1990, and welcome to the forums :)
Please try to manually delete upper/lower filter entries as described here (Resolution) and reboot:
The CD drive or the DVD drive does not work as expected on a computer that is running Windows Vista (http://support.microsoft.com/kb/929461) (also works on Windows XP/7/8/8.1).
