PEER_E_NOT_LICENSED
What the HRESULT means
PEER_E_NOT_LICENSED — HRESULT 0x80630004 marks the operating-system edition or installed peer feature does not authorize this legacy Peer-to-Peer protocol component to run.
Reconstruct the sequence
- Identify the first call among PeerGraphStartup, PeerGroupStartup and platform feature detection that returned the HRESULT.
- Preserve Windows edition and build, optional-feature inventory, product policy result, API family requested and whether the same binary works on a supported reference system.
- Correlate graph, group, PNRP and collaboration events with application cancellation, disconnect, shutdown and sign-out events.
- Run the narrow comparison: invoke only the startup routine on two clean systems with different supported-feature inventories, without changing application data.
The Windows Peer Infrastructure is composed of Graphing, Grouping, Identity Manager, PNRP and Collaboration APIs. Initialization and platform prerequisites must be established before object-specific calls can be interpreted.
Closest alternative diagnosis
PEER_E_CANNOT_START_SERVICE differs because a licensed component may still fail to start its service; licensing and service health must be diagnosed separately. The two codes can occur in one workflow, but they do not justify the same remediation.
Correction and proof
Treat this as a platform capability decision: use a supported OS/component combination or replace the dependency with a maintained networking design.
