Code 19 Registry Error
 

Yesterday I put Windows 2000 driver CD into my CD-Rom drive and suddenly my laptop doesn't "see" that drive anymore.

When I go to system/hardware, it's telling me that I'm having a Device Manager Error Code 19 and that my registry might be corrupted. I found this information that may possibly fix this problem for me, BUT I have no idea what an upperfilter or lowerfilter is. Can anyone help me shed some light on this??

~~~~~~~~~~~~~~~

Remove the Upperfilters and Lowerfilters values completely from the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Follow steps:

Start, Run, Regedit, find key, select key, expand it. then delete the to sub keys listed. I have no idea what they mean. I ran into the same problem after adding a BackPack-CDR to my system.
Good Luck

Re: Code 19 Registry Error
 

Sorry i dont know what they are either but if you follow the instructions above and just delete the filters your comp with recognise your cd drive again without any re-installing od drivers,(at least i didnt need to re-install any, i am running windows 2000 pro on a dell laptop)

all the best. lestat

Re: Code 19 Registry Error
 

Just type in 'Error code 39' in youtube search, my video solution will come up. It works for error codes 19, 31, 32 and 39.

Code 19 Registry Error
 

I was trying to install a new CD-RW (external) for my laptop and everyhting was fine but can't see the drive. Looked at device manager and found the drive is there but not working and thais was the erro
"Code 19 - Your registry might be corrupted"
I uninstalled the drive and restarted and reinstalled again but still same problem
Tried to update the drivers, still same problem.
Checked MS site but did not find any real solution (they said to change the bios or something like that).
Anyone know what is going on?

Re: Code 19 Registry Error
 

I have followed the steps and removed the Upper and Lower filters and I am still getting the error message: Configuration info (in the registry) incomplete, damaged (code 19). I have also uninstalled and reinstalled the hardware as well and that did not help either. Any suggestions?

Re: Code 19 Registry Error
 

Same problem...removed filters, uninstall/reinstall, etc...nothing helps. Checked the registry on a known good computer just for kicks and it does contain the "UpperFilters" component but no "LowerFilters"

Re: Code 19 Registry Error
 

I am having the same problem. I am running XP and installed a new cd-rom drive into my computer. I followed all of your helpful steps but my computer is STILL not recognizing the drive. Is there anything that you could suggest I do to resolve this problem?

Re: PLEASE HELP - Code 19 Registry Error
 

Thank you very much Carter. By following your hint, I fixed my problem with Canon EOS Rebel XT driver issue, where the hardware property shows Code 19 error. The Class Lower Filters of the detailed hardware property shows lvmvdrv, which caught my attention.
Initially, I removed the complete tree and it wouldn't work. Later on, I removed the value data "lvmvdrv" for the value name LowerFilters and it worked! I remember that I removed the driver of my Logitech web cam earlier. So I believe that's where the problem started.

Thanks again.

Re: Code 19 Registry Error
 

I'm having the same problem whereby removing the upper and lower filters and uninstalling/reinstalling the hardware does not correct the problem. Corrective suggestions?

Re: Code 19 Registry Error
 

Having same prob. PC lost CD and DVD burner icons and prob. 19 said they were not installed. I followed all the above steps and regained the icons for both but only the CD worlks--the DVD does not. How can I fix the DVD? PC says it is working properly in device mgr. but it will not burn or play---thanks in advance.

Re: Code 19 Registry Error
 

Hi,

My problem is not with the CD-ROM. I have a device through which I connect to my office VPN. But, when I insert the device in the USB port, it gives me the code 19 error stating that the device driver is not installed and you have to install the same to get it running.

Since, this is a registry error, will deleting upper filters and lower filters help?

But, where exactly do I have to do this? can anyone shed any light on this?

Regards,
Sanju

I want to thanks you for posting the solution. I had tried the Microsoft Fix It utility that was designed to fix the problem but did not.
This worked perfectly.
Only thing to add is to backup the Registry first (always a good practice).
And you need to reboot to see the change.

Regedit worked with MS fixit
 

I have Dell and got this code 19 error when I tried to reinstall drivers from the Dell delivered driver CD after I reinstalled the OS.
Searched for a while to find a solution to no avail until I came upon this.

I am running Vista home edition

So in summary

1. Start,
2. Run, (for vista home type cmd in the run box)
3. Regedit,
4. export registry,
5. find key,
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
6. select key,
7. expand key
8. Remove the Upperfilters and Lowerfilters values completely
9. reboot/restart


Previously I ran the Microsoft Fixit solution for code 19,that did not work for me,
but for those of you that this is not working for maybe the combination will do the trick.
