NS_E_LICENSE_EXPIRED
Why the symbolic result matters
When NS_E_LICENSE_EXPIRED is returned, the system has already established that the product-level authorization has passed its validity end, before content rights are evaluated. The subsystem producing this result is Windows Media licensing, not the media decoder; it performs the feature or media-operation licensing gate that decides whether the installed product and the current content-rights object permit the requested operation.
Before changing the machine, read the product-license validity interval and system time from the same host.
Objects involved
Do not separate this result from its owning state: application feature entitlement, media license, requested operation, validity interval and rights flags. The diagnostic record for this HRESULT is the API operation, feature identifier, license identity, validity dates and rights returned for that exact operation.
A later generic error must not replace this evidence: the original condition remains that the product-level authorization has passed its validity end, before content rights are evaluated.
Cause and successor state
When documenting this result, state the rejected input and the expected successor state. The rejected input is demonstrated when you read the product-license validity interval and system time from the same host; the successor becomes reachable after you renew or replace the expired product entitlement and then recreate the media operation. The result model is suitable for a regression fixture because its expected state change is observable without weakening the DRM policy.
What separates this code
| Field | Value |
|---|---|
| Direct check | read the product-license validity interval and system time from the same host |
| Policy input | requested action plus the exact license, certificate, profile, output or registration property evaluated by it |
| Temporal state | trusted/system time, validity interval, request sequence and retry number when they influence it |
| Lower result | the earliest store, network, cryptographic, driver or provider status preceding the final it wrapper |
| Owner | operation, API/callback, object or session identifier, and component/device version associated with it |
Adjacent HRESULTs
| Result | Why it points elsewhere |
|---|---|
NS_E_NOT_LICENSED | the installed application has no entitlement for the requested Windows Media feature |
NS_E_LICENSE_REQUIRED | the media operation reached a content-protection gate with no usable license object |
NS_E_LICENSE_OUTOFDATE | a license exists but its time or revision constraints no longer authorize this media object |
First failure versus cleanup
The established fact is that the product-level authorization has passed its validity end, before content rights are evaluated. That fact does not independently establish damaged media bytes, a missing decoder, a generally broken network, or invalid rights for every other action.
If the Player, encoder, setup program or device layer later emits a broader error, retain it as the first specific result. The object and operation attached to it are usually more diagnostic than a later cleanup or user-interface summary.
Verification sequence
- Preserve it and
0xC00D00D4before cleanup, fallback or another media item changes the context. - Compare the failure with a known-good case that changes only the property named by this condition: the product-level authorization has passed its validity end, before content rights are evaluated.
- Apply the narrow correction for this HRESULT: renew or replace the expired product entitlement and then recreate the media operation.
- Associate it with its current Windows Media licensing object and the requested action.
- Run the direct check for this HRESULT: read the product-license validity interval and system time from the same host.
- Repeat the same action with the same content/device identity and verify that it is not replaced by another policy or trust failure.
Safe recovery
Repair the owner of the check: renew or replace the expired product entitlement and then recreate the media operation. Success means that the same requested action is accepted after that precise state change, not merely that another file or device happens to work.
- Evidence for this HRESULT is easy to destroy; Do not assume that installing a codec changes licensing state; codec availability and permission to use the feature or content are independent checks.
- Do not alter trusted time, revocation enforcement, certificate validation or output policy merely to suppress it; that bypasses the decision instead of correcting its input.
- Retain one failing artifact and one corrected artifact so the resolution of it can be regression-tested.
A useful automated test
For the final it test, keep the content KID or file hash, requested action, user/account, device identity and output route unchanged wherever they apply.
