NS_E_WMP_DRM_LICENSE_UNUSABLE

Start with the producing object

NS_E_WMP_DRM_LICENSE_UNUSABLE means a located license cannot be applied to this content/action despite being present. 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 KID, machine binding, rights, security requirements and revocation state.

Practical diagnostic path

Preserve this result and 0xC00D1206 before cleanup, fallback or another media item changes the context.
Apply the targeted fix: replace the unusable license with one issued for this content and environment.
Associate this result with its current Windows Media Player rights processing object and the requested action.
Compare the failure with a known-good case that changes only the property named by this condition: a located license cannot be applied to this content/action despite being present.

Relevant runtime state

A complete incident ties together content KID and header, license-store entry, requested action, acquisition URL, user/store context, secure clock and DRM component generation; the minimum correlation set is the content KID, requested action, license-state query, acquisition callback sequence, server response category and the first lower-level DRM HRESULT.

This evidence matters because the rejected condition is specifically that a located license cannot be applied to this content/action despite being present.

One-variable comparison

It should be modeled as a failed precondition, not as an arbitrary media exception. Demonstrate the precondition by choosing to compare KID, machine binding, rights, security requirements and revocation state, and remove it by choosing to replace the unusable license with one issued for this content and environment. The result comparison should preserve content and device identity so success cannot be attributed to testing a different asset.

What another code would mean

Result	Why it points elsewhere
`NS_E_WMP_DRM_LICENSE_NOTACQUIRED`	the Player completed or abandoned acquisition without installing a usable matching license
`NS_E_WMP_DRM_LICENSE_NOTENABLED`	the license exists but its start condition has not yet become true
`NS_E_WMP_DRM_LICENSE_CONTENT_REVOKED`	the issuer has revoked authorization for the protected content or license

Do not diagnose the wrong layer

A located license cannot be applied to this content/action despite being present.

What success looks like

The next attempt becomes meaningful only after you replace the unusable license with one issued for this content and environment.

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.
