VirtualDVD Troubleshooting Guide

Cause of the Problem

The main cause of issues in VirtualDVD is usually a conflict with third-party CD-ROM-related filter drivers installed on the system, such as UpperFilters or LowerFilters. These drivers can interfere with the normal operation of virtual drives.

How to Fix It

You can resolve the issue by following the steps below. Please proceed carefully.

1. Open the Registry Editor

• Click the Windows Start menu.
• Type regedit in the search box or Run dialog, then click OK to open the Registry Editor.

2. Go to the Registry Path

• In the Registry Editor, navigate to the following path:
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e965-e325-11ce-bfc1-08002be10318}
• This path contains settings related to the CD/DVD drive class.

3. Delete the Filter Drivers

• If you see UpperFilters or LowerFilters in that location:
• Right-click each entry and select Delete.
• Before deleting them, it is recommended to back up any important data.
• Deleting both entries increases the likelihood of resolving the issue completely.

4. Restart Windows

• Close the Registry Editor.
• Restart your computer to apply the changes.
• After restarting, run VirtualDVD again and check whether it works normally.

Additional Notes

• Editing the registry can have a significant effect on your system, so be careful not to delete the wrong entries.
• If the problem continues, contact VirtualDVD support or try updating to the latest version.
• Removing third-party software, such as other virtual drive programs, may help prevent additional conflicts.

Most filter driver-related issues can be resolved by following the steps above. Proceed carefully so you can use VirtualDVD smoothly!
