NS_E_WMP_DRM_LICENSE_NOTENABLED

Failure scope

For NS_E_WMP_DRM_LICENSE_NOTENABLED, the failed contract is that the license exists but its start condition has not yet become true. Within Windows Media Player rights processing, this result is raised while processing the Player layer that opens protected media, queries the local license state, performs silent or interactive rights acquisition, validates DRM components and applies play, burn or sync restrictions.

Before changing the machine, compare trusted time and any first-use/start-date condition with the current action.

Data worth retaining

The object graph behind this result includes content KID and header, license-store entry, requested action, acquisition URL, user/store context, secure clock and DRM component generation. A trace should retain the content KID, requested action, license-state query, acquisition callback sequence, server response category and the first lower-level DRM HRESULT.

A later generic error must not replace this evidence: the original condition remains that the license exists but its start condition has not yet become true.

The transition to retest

A useful failure model links cause and recovery: the license exists but its start condition has not yet become true. Verify that model when you compare trusted time and any first-use/start-date condition with the current action, then make the smallest change needed to wait for the valid interval or obtain a license with an appropriate start condition.

Verification inputs

Field	Value
Owner	operation, API/callback, object or session identifier, and component/device version associated with this result
Direct check	compare trusted time and any first-use/start-date condition with the current action

Different owners, similar dialog

Result	Why it points elsewhere
`NS_E_WMP_DRM_LICENSE_EXPIRED`	the matching Player license is outside its permitted usage interval
`NS_E_WMP_DRM_LICENSE_NOTACQUIRED`	the Player completed or abandoned acquisition without installing a usable matching license
`NS_E_WMP_DRM_LICENSE_UNUSABLE`	a located license cannot be applied to this content/action despite being present

Separate cause from wrapper

The license exists but its start condition has not yet become true.

Test without erasing evidence

Preserve it and 0xC00D1205 before cleanup, fallback or another media item changes the context.
Apply the targeted fix: wait for the valid interval or obtain a license with an appropriate start condition.
Associate this result with the current Windows Media Player rights-processing object and the requested action.
Run the direct check: compare trusted time and any first-use/start-date condition with the current action.
Compare the failure with a known-good case that changes only the property named by this condition: the license exists but its start condition has not yet become true.

When a retry is valid

Recovery should change the failed precondition by choosing to wait for the valid interval or obtain a license with an appropriate start condition.

Preserve the evidence before making changes. Do not reset the local DRM store before recording the content KID and license-state result; a reset can turn a precise rights or signature failure into a generic missing-license condition.
