Virtual Device Driver format in the registry                                      is invalid. Choose 'Close' to terminate the application.
you have a corrupted registry value at:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers\VDD.

NOTE: You probably installed a 16-bit program that is not Windows 2000 compliant.

To fix the problem:

1. Using Regedit.exe, Delete the VDD value name.

2. Using Regedt32.exe, On the Edit menu, Add Value name VDD as a REG_MULTI_SZ data type. Don't enter any data in the Multi-String Editor. Press OK and exit Regedt32.
