NS_E_DRM_APPCERT_REVOKED
What NS_E_DRM_APPCERT_REVOKED means
NS_E_DRM_APPCERT_REVOKED is Windows Media DRM HRESULT 0xC00D2752. Its symbolic name identifies an application-certificate revocation boundary. Microsoft’s general error-code table exposes only a generic DRM support message for this value, so the symbolic result and the operation that returned it are more useful than the user-facing text alone.
WMDRM uses revocation information to reject components or applications that are no longer trusted for protected-content operations. Treat this result as a trust decision, not as evidence that the media file, license store, or network is corrupt.
What to check
- Record the API or callback that first returned
0xC00D2752, the application/component version, and the certificate or application identity involved. - Capture the revocation-list/update state and the first related DRM status before the player or wrapper converts it to a generic playback error.
- Compare the failing binary with the currently supported signed build. Replacing license files or deleting the DRM store does not repair a revoked application certificate.
Recovery
Use a current trusted application/component or the vendor’s supported update path. Retry only after the application certificate or revocation state has actually changed; repeated attempts with the same revoked component should produce the same result.
Related HRESULTs
NS_E_DRM_CERTIFICATE_REVOKED refers to a revoked client certificate, while NS_E_DRM_INVALID_APPCERT identifies an invalid application-certificate condition. Preserve the exact symbolic code because the public messages for these older WMDRM failures are often less specific than the names.
