Installation problem in Windows NT4/2000/XP
Whilst running the InstallShield setup.exe program (or any 16-bit program) in Windows NT4/2000/XP, this error message may appear in a "16bit Windows Subsystem" dialogue box :
SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers VDD Virtual Device
Driver format in the registry is invalid.
You will be given the option to "Close", which terminates the application, or "Ignore" which allows the application to run normally (hopefully!).
This error indicates that the Microsoft® Windows® operating system components needed to run the setup.exe install program, are either not present on your computer, or have become corrupted.
The Official Solution
To resolve this issue, contact your computer manufacturer or Microsoft. For more information, see knowledge base articles Q222975 and Q165214 on Microsoft's Web site.

This error is caused due to an unknown problem that exists in the Registry.
Clicking on Ignore is a temporary solution that should allow a 16 bit application to run. The permanent solution is to fix your Registry by performing the following:
