NS_E_DRM_SECURITY_COMPONENT_SIGNATURE_INVALID
The exact DRM condition
NS_E_DRM_SECURITY_COMPONENT_SIGNATURE_INVALID is Windows Media DRM HRESULT 0xC00D2760. It identifies the digital rights management security upgrade component could not be validated. Contact microsoft product support. The useful scope is the consent-driven security update that replaces a generic DRM component with an individualized component tied to the computer and then reports progress asynchronously; it is not a generic statement that the media player, network or file system failed.
Record the exact API, object state, input identity and first lower-level result associated with this failure.
The surrounding protocol and store state
Individualization modifies DRM security components and should be distinguished from ordinary license acquisition. A failed or incomplete individualization can leave the client unable to satisfy licenses that require the upgraded component even though unprotected content still works.
Evidence worth preserving
- Protected identity: user consent and cancellation point.
- Operation state: whether the application is already individualized for the required level.
- Persistence or transport: individualization state and completion callback.
- Security context: security-component version before and after the attempt.
- Correlation point: download/service response and signature validation result.
Related codes and the diagnostic split
| Result | Different condition |
|---|---|
NS_E_DRM_INDIVIDUALIZATION_INCOMPLETE | A problem occurred during the security upgrade. Try again later. |
NS_E_DRM_INDIVIDUALIZE_ERROR | The security upgrade failed. Try again later in the Windows Media DRM client |
NS_E_DRM_INDIVIDUALIZING | A security-component individualization operation is already in progress. |
Correcting the producing condition
Resolve the underlying condition directly: correct the producing DRM state or input and retry with a fresh operation object. A player reinstall, reboot or new license request is useful only when it changes the condition “security-component signature validation failure” and can be verified against the original evidence.
Representative case: The application reaches this path and receives this exact HRESULT before the higher-level media action can complete.
Actions that do not prove a fix
- Avoid replacing individualized binaries manually or suppressing signature validation.
- Avoid repeating security upgrades concurrently or without waiting for the completion status.
- Do not reduce this result to “DRM failed” in telemetry; retain the HRESULT, symbolic name, operation and object identity.
Regression check
Repeat the operation that originally returned this result. Assert the exact HRESULT at the producing API in the failing “security-component signature validation failure” 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 “security-component signature validation failure”.
Code-specific operational note
The user-facing message “The Digital Rights Management security upgrade component could not be validated. Contact Microsoft product support.” describes the visible condition but does not identify the producing API, object instance, or protected identity by itself.
