The problem is that when Redemption.dll is customized, only the registry
names of the Redemption classes are changed, but not the underlying type
library (embedded as a resource in the dll).
When VS tries to locate the registry keys, it looks for the original class
names stored in the type library, not the modified class names.
If you are using registry-free COM, there is absolutely no reason to also
customize the dll since it will never be registered in the registry, and no
other app will ever see or use it.
