NS_E_DRM_UNABLE_TO_CREATE_CERTIFICATE_OBJECT
Diagnosing NS_E_DRM_UNABLE_TO_CREATE_CERTIFICATE_OBJECT
0xC00D2786 isolates failure to construct the WMDRM certificate object used by the protected operation. Distinguish failure to create the certificate-handling object from a later certificate-chain or revocation decision.
Evidence to capture
- the certificate-object factory/interface call and first nested HRESULT;
- certificate or application-certificate identity by thumbprint/hash and declared type, without logging private material;
- runtime/stub-library versions and the parent DRM object generation;
- property initialization order and any trust/validation status already available before creation.
Focused test
Create the certificate object with a known-valid certificate identity on the same runtime. A successful control points to the original certificate metadata or initialization sequence; failure with both inputs points to the DRM component or its loaded version rather than the media file.
Correction and verification
Repair the certificate input or component initialization, recreate the object, and then repeat the operation that needs certificate services. The fix is proven when construction succeeds and certificate validation can proceed to its own result.
