VDS_E_INVALID_PROVIDER_CLSID

VDS_E_INVALID_PROVIDER_CLSID is a provider-registration identity error. The CLSID names the COM class VDS must instantiate; it is different from the persistent provider object ID and the version GUID reported later in VDS_PROVIDER_PROP.

Validate each provider GUID by role

Reject GUID_NULL before registration or configuration is committed.
Confirm that the CLSID is registered for the correct executable or in-process server architecture.
Keep the provider ID and version GUID separate from the COM class identity.

Copying one GUID into all provider fields can produce a syntactically valid but semantically broken registration. Diagnose COM activation separately from provider discovery: a valid provider ID cannot compensate for a missing CLSID registration, and changing display names does not affect class activation.
