NS_E_DRM_LICENSE_INVALID_XML
How to classify this result
The symbolic result NS_E_DRM_LICENSE_INVALID_XML narrows 0xC00D2725 to protected content header, keys and cryptographic processing. In practical terms, the license is corrupted. Acquire a new license; the producing layer is the path that parses the DRM header, selects a KID and algorithm, validates signed data, creates cryptographic objects and encrypts or decrypts protected media samples.
Record the exact API, object state, input identity and first lower-level result associated with this failure.
How to prove the condition
- Locate the earliest API return, callback or event containing this result and
0xC00D2725. - Identify the exact content, license, store, device or migration object instance involved in “license invalid xml”.
- Determine whether “license invalid xml” 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 this failure.
- Make one targeted change — 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 malformed content header, an invalid license XML document and a decryption failure occur at different boundaries and require different replacement artifacts. The second relevant rule is that protected content should be identified by hashes and KIDs in support records; content keys and complete license blobs should not be exposed.
Diagnostic inputs that separate the causes
- Protected identity: KID, license ID and key-selection result.
- Operation state: algorithm, key length and coding object type.
- Persistence or transport: signature or certificate validation status.
- Security context: first failing sample offset rather than only the player-level message.
- Correlation point: ASF/DRM header bytes and declared version.
Common but unsafe responses
- Avoid publishing content keys, full license blobs or decrypted media while collecting diagnostics.
- Avoid assuming a codec reinstall can repair a malformed DRM header or a cryptographic key mismatch.
- Do not reduce this result to “DRM failed” in telemetry; retain the HRESULT, symbolic name, operation and object identity.
What a supported fix should change
To correct this, correct the producing DRM state or input and retry with a fresh operation object. Preserve the original content/header, store or migration material until the operation succeeds and survives a fresh application object or required restart.
Representative case: The application reaches the license invalid xml path and receives this exact HRESULT before the higher-level media action can complete.
Do not merge these HRESULTs
| Result | Different condition |
|---|---|
NS_E_DRM_DECRYPT_ERROR | The media file is corrupted. Contact the content provider to get a new file. |
NS_E_DRM_ENCRYPT_ERROR | WMDRM failed while performing an encryption operation. |
NS_E_DRM_KEY_ERROR | The requested action cannot be performed because a problem occurred with the Windows Media Digital Rights Management (DRM) components on your computer. |
How to know the fix is real
After the repair, recreate the WMDRM object and run the smallest reproducer. Confirm that 0xC00D2725 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 user-facing message “The license is corrupted. Acquire a new license.” describes the visible condition but does not identify the producing API, object instance, or protected identity by itself.
