1. Click Start, type regedit in the Start Search box, and then click regedit in the Programs list. If you are prompted for an administrator password or confirmation, type your password, or click Continue. 2. Locate, and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} Caution There can be many instances of the registry subkey that is mentioned in step 2. You must make sure that you are in the appropriate registry subkey before modifying the UpperFilters and the LowerFilters values. To verify that you are in the appropriate registry subkey, make sure that the Default data value is DVD/CD-ROM and the Class data value is CDROM. 3. In the right pane, right-click UpperFilters, and then click Delete. 4. Click Yes to confirm the removal of the UpperFilters registry entry. 5.

That means you have a missing driver.

The solution is to load the missing driver.

Use PC Pitstop to help you determine which driver is missing.

Acer dvd driver missing acer ferrari 400 dvd uj-845-c


CD/DVD drive drivers are Operating System generic drivers and need not to be installed explicitly. The CD/DVD drive drivers are installed along with the Operating System and can be reinstalled automatically at next restart, if missing.

Check in the Device Manager under the "CD/DVD drive" category if there is any device listed there and having exclamation mark. If there is any exclamation mark visible beside the CD/DVD drive name then right click on it and restart the Computer.

Restarting the Computer will reinstall the CD/DVD drive driver thus causing it to work normally.

Hi,
Please go through the below provide steps.
Fixing Code 39 Error
If your CD-ROM drive is not visible in My Computer, you may see the following error message displayed with the CD or DVD drive item in your Device Manager. (Steps to open Device Manager are discussed later in the article.)
"Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"
Using Device Manager
To fix this error, first try to update the driver from the Device Manager. To open Device Manager, right-click My Computer on your Desktop, and then on the Hardware tab, select the Device Manager button.
In the Device Manager window, identify the CD or DVD drive item (with Yellow exclamation mark), right-click on it and select Update Driver. Follow the screen instructions to update the device driver and restart your PC.
Using Registry Editor
If updating the driver does not resolve the problem, it indicates that there is a problem in the registry. To fix this problem, you may have to remove a few keys from the registry.
Note: Be careful while working with the registry editor because changes done to the registry using the Registry Editor are irreversible and mistakes can leave you with more problems than when you started. Therefore, it is recommended that you make a backup of the registry before proceeding with the changes.
After you have removed the registry keys listed below, you will have to reinstall all applications that you use for CD or DVD recording to make them work properly.
To fix the error by editing the registry, perform the following steps:
  1. Exit and close all applications currently running on your PC.
  2. On Start > Run type Regedit and press the Enter key.
  3. Next, navigate to the following registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}
  4. Delete any of the following registry entries if they exist under this key:
    • LowerFilters
    • LowerFilters.bak
    • UpperFilters
    • UpperFilters.bak
  5. Restart your PC and open My Computer to ensure that the CD-ROM drive is visible.
  6. Also, open the Device Manager again to ensure that the yellow exclamation mark and the error code is now gone.
  7. Restart your PC and open My Computer to ensure that the CD-ROM drive is visible.
  8. Also, open the Device Manager again to ensure that the yellow exclamation mark and the error code is now gone.
Thank you........
