CD/DVD driver can't load successfully in Win 7

[strells]

Up until today, I had zero problems with the virtual CD/DVD drive. Now, I can't mount any disks or any images. Checking the Device Manager, I get the little warning symbol on the "Matshita DVD-R UJ-898 ATA Device". The properties say: Windows cannot start this hardware device because its configuration information (in the registry is incomplete or damaged. (Code 19)

I've tried removing and re-adding the CD/DVD drive in the PD VM configuration, I've tried removing and reinstalling Parallels Tools (had to call Parallels support to find out how to do this since I can't mount an .iso image). I've tried changing how the drive is connected. I've run the Win 7 troubleshooter. No matter what I do, I cannot get the drive back.

Here are the only things I can think of left: I did run Windows Update this morning and installed about a month's worth of security updates. I'm also using Virtual Clone Drive by Slysoft to mount multiple .iso images. Strangely enough, in the Device Manager, "Elby Clonedrive SCSI CdRom Device" also indicates a registry problem. Uninstalling that doesn't fix the problem either.

I think I'm left with reinstalling Windows, but I'm not even sure that will do anything since this seems to be just a driver issue.

Any ideas at all?

Unfortunately, that's a Vista-only solution, not Win 7. I did not have the "LowerFilters" in my registry, and Parallels support recommended against deleting just the "UpperFilters". I ended up reinstalling Windows, which did fix the problem.

But why can't Microsoft let you reinstall the OS without trashing all your programs and settings? A rant for another day, I guess...

Had same problem - found solution for me

So I had the same problem and found a Website that gave the following solution:

Re: information (in the registry) is incomplete or damaged. (Code 19)
Problem solved, and here's howgot this information from Ask Me Help Desk)

These instructions are for XP but it works in Vista too [AND WIN 7 FOR ME]. The difference being how you get to the Command Promp and plus sign (+) vs. arrows.

1. Click Start.
2. Click Run.
3. In the "Open" field type REGEDIT.
4. Click OK.
5. Click "File" in the menu bar.
6. Click "Export" from the drop down menu this will open a new box.
7. Click the down arrow beside "Save In" and select "Local Disk (C".
8. In the File Name field type BACKUP.REG.
9. Verify that under the Export Range, that the radio button is beside "All".
10. Click Save.
11. Click the plus sign (+) beside HKEY_LOCAL_MACHINE.
12. Click the plus sign (+) beside System.
13. Click the plus sign (+) beside CurrentControlSet.
14. Click the plus sign (+) beside Control.
15. Click the plus sign (+) beside Class.
16. In the left hand window pane click on {4D36E965-E325-11CE-BFC1-08002BE10318} to select that key.
17. In the right hand window pane select the UpperFilters registry key and press the delete key on the keyboard.
18. Confirm with an OK.
19. In the right hand window pane select the LowerFilters registry key and press the delete key on the keyboard.
20. Confirm with an OK.
21. Click the "X" in the upper right hand corner of the Registry Editor window to close it.

Restart your Computer in order for the registry - fix to work.

For me, I didn't have a "lowerFilter" but I did delete the upper, restarted the machine, and suddenly I had access to that CD ROM drive again, which allowed me to reinstall parallels tools, and fixed my even bigger problem of having several hardware devices (including my NIC (Internet)) not have drivers in my Device Manager.

I hope that this helps others as well.

This is somewhat related, so I'll post it here. (Parallels 8, Windows 7 64-bit). I had been using an ISO image and went back to use the Real CD-DVD drive. Two possibilities in the sub-menu: "Default CD/DVD" or "MATSHITA DVD-R UJ-898" I picked "Default CD/DVD" and Windows 7 64-bit busily tried installing drivers, but ended up with"No driver for MATSHITA DVD-R UJ-898 ATA Device". However, if I explicitly pick "MATCHITA DVD-R UJ-898" no driver installation attempt and it works fine.
