VDD

[Jim D]

When trying to install certain software, when I put a
CDROM, I get the message:

16bit WINDOWS Subsystem

SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers.VDD.
Virtual Device Driver format in the registry is invalid.
Choose 'Close' to terminate the application.

CLOSE IGNORE


What do I have to do to fix this?

Thanks
Jim

You CDROM installer is starting a 16 bit process.

You had software that you removed without uninstalling it leaving its VDD
behind in the registry. In other words, the VDD file the system was trying
to load for the 16 bit process was no longer there because you manually
deleted the files.

We have the same issue with customers who don't use the uninstaller for our
product, but instead manually delete the files. When a dos window is open,
POOF, you get this error.

So we gave them a special tool to remove the VDD from the registry.

You need to delete it too from the registry.

HOWEVER WARNING!

It is not that simple as it is a REG_MULTI_SZ type and it may have other
VDDs in the bunch.

Check out the location in the registry:

HKEY_LOCAL_MACHINE

SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers

and see what it has to the VDD key.

If its just one item, I think you go delete it the data in it. That should
do it.

But there is MORE than one! You need to figure out which one has to be
removed from the group. If you delete them all, you may break things!

PS: DON"T BLAME ME IF YOU SCREW UP THE REGISTRY! BE CAREFUL OF WHAT YOU ARE
DOING THERE!
