SL_E_INVALID_LICENSE
Where this result is produced
SL_E_INVALID_LICENSE is HRESULT 0xC004F01F. It belongs to the local Software Protection Platform. Its narrow boundary is: the selected license object fails general structural or semantic validation.
Condition to preserve: The documented condition is “The Software Licensing Service determined that the license is invalid.” A comparison run should change that state, not an unrelated component setting.
Windows reports “The Software Licensing Service determined that the license is invalid”.
Minimum diagnostic record
| Different result | If the experiment instead proves “the caller supplies a value whose type differs from the type declared by the license property”, diagnose that condition separately rather than treating it as this HRESULT. |
Recovery without broad resets
To correct this using supported mechanisms, capture license identity, package version and first parser/verifier event and reinstall the official artifact.
