VDS_E_INVALID_PROVIDER_ID
VDS_E_INVALID_PROVIDER_ID means the persistent provider identity is missing. VDS uses this object ID to distinguish providers during enumeration and notifications; it is not the COM CLSID and should remain stable for the same provider implementation.
Check provider identity persistence
- Generate or retrieve a non-null provider object GUID from provider metadata.
- Keep the same provider ID across refreshes and service restarts.
- Do not substitute the version GUID, subsystem ID or class ID for the provider ID.
An unstable provider ID makes cached references and notifications ambiguous even if COM activation succeeds. When comparing installations or logs, record all three identities: CLSID, provider object ID and version GUID. Correct the registration source rather than patching the value only in memory.
