NS_E_DRM_SECURE_STORE_NOT_FOUND
How to classify this result
The symbolic result NS_E_DRM_SECURE_STORE_NOT_FOUND narrows 0xC00D274A to local license store, secure store and machine binding. In practical terms, the secure store not found operation failed at its documented DRM boundary; the producing layer is the protected repositories that hold licenses and DRM state, together with the hardware and checkpoint data used to bind that state to one installation.
The built-in message summarizes the user-visible outcome, while the symbolic phrase “secure store not found” preserves the exact WMDRM boundary for diagnosis. For this code, the proof step is to record the exact API, object state, input identity and first lower-level result associated with secure store not found.
How to prove the condition
- Locate the earliest API return, callback or event containing this result and
0xC00D274A. - Identify the exact content, license, store, device or migration object generation involved in “secure store not found”.
- Determine whether “secure store not found” occurred before network exchange, during response validation, while enforcing policy, or while committing protected state.
- Perform the code-specific check: record the exact API, object state, input identity and first lower-level result associated with secure store not found.
- Make one narrow correction — correct the producing DRM state or input and retry with a fresh operation object — and repeat the same producing operation.
Which component owns the failure
Do not flatten this result into a generic DRM error. 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. The second relevant rule is that machine-bound state cannot be diagnosed safely by copying store files between computers or by deleting the original before evidence is preserved.
Diagnostic inputs that separate the causes
Capture the first occurrence before retry or teardown changes state. The smallest useful record contains:
- Code-specific proof: record the exact API, object state, input identity and first lower-level result associated with secure store not found.
- Protected identity: first store API call that failed: open, enumerate, save, close or query.
- Operation state: license identifier and content key identifier (KID).
- Persistence or transport: store path, file generation, access result and underlying system error.
- Security context: hardware identity and the last hardware or operating-system change.
- Correlation point: checkpoint, secure-store and registry persistence sequence.
Prefer IDs, hashes, sizes, and timestamps. Never log keys, passwords, licenses, or decrypted media.
What a supported fix should change
The corrective direction is to correct the producing DRM state or input and retry with a fresh operation object. Preserve the original content/header, store or migration material for it until the operation succeeds and survives a fresh application object or required restart.
Representative case: The application reaches the secure store not found path and receives this exact HRESULT before the higher-level media action can complete.
Do not merge these HRESULTs
| Result | Different boundary |
|---|---|
NS_E_DRM_HARDWARE_INCONSISTENT | Stored DRM state no longer matches the current hardware identity. |
NS_E_DRM_GET_LICENSESTRING_ERROR | The client cannot obtain the serialized license string from the selected record. |
NS_E_DRM_GET_LICENSE_ERROR | Retrieval of a license from the local store failed after lookup began. |
Order the result event chain by timestamp; prefer the earliest specific result.
How to know the fix is real
After the repair, recreate the WMDRM object and run the smallest reproducer for it. Confirm that 0xC00D274A no longer occurs, that the intended license action completes, and that no store, certificate, clock or migration warning replaces it.
Code-specific operational note
The symbolic phrase “secure store not found” is the important search and telemetry key for it. Keep it beside the exact value 0xC00D274A; the official message “A problem has occurred in the Digital Rights Management component of this application. Try to acquire a license again.” is useful to users, but it does not identify the producing API, object generation or protected identity on its own.
