NS_E_DRM_LICENSE_STORE_SAVE_ERROR
Meaning beyond the player message
When the client returns NS_E_DRM_LICENSE_STORE_SAVE_ERROR (0xC00D2714), the relevant condition is an acquired or updated license could not be committed to the local license store. This result belongs to local license store, secure store and machine binding, specifically the protected repositories that hold licenses and DRM state, together with the hardware and checkpoint data used to bind that state to one installation.
Separate server success from the subsequent local save result and record free space and store generation.
Why the producing layer matters
Two platform rules frame this result. A license is stored in the protected local license store after acquisition; a store failure is therefore distinct from a server refusing to issue a license. Machine-bound state cannot be diagnosed safely by copying store files between computers or by deleting the original before evidence is preserved.
Triage without destroying evidence
- Prove the boundary by ensuring you can separate server success from the subsequent local save result and record free space and store generation, with.
- After you restore reliable store persistence and repeat acquisition only after reconciling the prior response, verify both the requested right and the final store/device state.
Minimum incident record
- Protected identity: checkpoint, secure-store and registry persistence sequence.
- Operation state: first store API call that failed: open, enumerate, save, close or query.
- Persistence or transport: license identifier and content key identifier (KID).
- Security context: store path, file generation, access result and underlying system error.
- Correlation point: hardware identity and the last hardware or operating-system change, with.
Recovery at the right layer
Resolve the underlying condition directly: restore reliable store persistence and repeat acquisition only after reconciling the prior response. A player reinstall, reboot or new license request is useful only when it changes the condition “license store save error” and can be verified against the original evidence.
Representative case: The server returns a license, but the client fails while saving it locally.
Why the symbolic name matters
| Result | Different condition |
|---|---|
NS_E_DRM_SECURE_STORE_ERROR | The protected secure-state repository cannot complete the requested operation. |
NS_E_DRM_SECURE_STORE_UNLOCK_ERROR | The client cannot unlock secure-store state required for DRM processing. |
NS_E_DRM_LICENSE_STORE_ERROR | The local license repository failed before a particular license operation could complete. |
Completion criteria
Repeat the operation that originally returned it. Assert the exact HRESULT at the producing API in the failing “license store save error” fixture; then change only the relevant precondition and confirm that the corrected run completes without substituting a neighboring DRM result. After correcting it, verify the requested action and the final license-store, secure-clock, device or migration state relevant to “license store save error”.
Code-specific operational note
The user-facing message “License acquisition did not work. Acquire a new license or contact the content provider for further assistance.” describes the visible condition but does not identify the producing API, object instance, or protected identity by itself.
