TYPE_E_CANTLOADLIBRARY on Windows XP

[pat...@ingr.com]

Greeting,

I am building an NT Service using VB.net from Visual Studio 2005. I
have a client that talks to the Service and the service burns the CD.
The burn toolkit comes from Ahead and is called Nero (version
6.6.1.15).

When compiled and run on Windows 2000 (Service Pack 4) it runs great.
When compiled and run on Windows XP I get the following error:

Unable to cast COM object of type 'System.__ComObject'
to interface type 'NEROLib.INeroDrive6'.
This operation failed because the QueryInterface call on the COM
component for
the interface with IID '{31928EE4-8847-49FD-9CD6-2B3D6BD073D9}' failed
due to
the following error: Error loading type library/DLL. (Exception from
HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)).

Why might this be?

Thanks.
