NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT
The exact DRM condition
0xC00D2784 maps to NS_E_DRM_UNABLE_TO_CREATE_INMEMORYSTORE_OBJECT. Read it as a result from Windows Media DRM client API contract and object lifecycle: the DRM runtime cannot create the in-memory-store object required for this operation. Keeping the “unable to create inmemorystore object” boundary intact prevents a later playback message from hiding the original DRM failure.
Place in the DRM workflow
The workflow around this result matters: the DRM client exposes different objects for license management, individualization, encryption, backup, metering and device registration; failure to create one object does not prove that all DRM state is damaged. In addition, many operations are asynchronous and stateful, so object lifetime and completion ordering are part of the API contract.
A useful investigation order
- Prove the boundary by ensuring you can record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT.
- After you correct component/version or initialization state and create a fresh in-memory-store object, verify both the requested right and the final store/device state.
State to capture before retry
- Code-specific proof: record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT.
- Protected identity: SDK/runtime version and linked DRM stub library.
- Operation state: property name, type, size and initialization order.
- Persistence or transport: operation state, callback sequence and cancellation owner.
- Security context: first inner HRESULT before an application replaces it with a generic error.
- Correlation point: exact interface method and object type being created.
Targeted fix
Resolve the underlying condition directly: correct component/version or initialization state and create a fresh in-memory-store object. A player reinstall, reboot or new license request is useful only when it changes the condition “unable to create inmemorystore object” and can be verified against the original evidence.
Representative case: The application reaches the in-memory-store stage but object construction fails before any content or server work begins.
Nearby results with different meanings
| Result | Different condition |
|---|---|
NS_E_DRM_STUBLIB_REQUIRED | The application did not provide the required DRM stub library identity. |
NS_E_DRM_UNABLE_TO_CREATE_CERTIFICATE_OBJECT | The DRM runtime cannot create the certificate object required for this operation. |
NS_E_DRM_BB_UNABLE_TO_INITIALIZE | The DRM root-of-trust component cannot initialize. |
Verification after correction
Repeat the operation that originally returned it. Assert the exact HRESULT at the producing API in the failing “unable to create inmemorystore object” 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 “unable to create inmemorystore object”.
What the missing object would have owned
The in-memory store object normally holds temporary DRM records used before or instead of protected persistence. Object creation fails before that responsibility can be transferred to a live interface, so later player or server messages are secondary.
For this object specifically, preserve the owner operation, record identities, lifetime and transition to persistent state. A successful fix should create a new in-memory store object and then complete its first real operation, not merely make the factory call return a different generic error.
