SL_E_POLICY_CACHE_INVALID
How to interpret this HRESULT
When SL_E_POLICY_CACHE_INVALID returns 0xC004F028, diagnosis has reached the local Software Protection Platform. Specifically, the compiled or cached licensing policy cannot be trusted or parsed.
The local Software Protection Platform models applications, products, Activation IDs, license packages, policies and the service state separately. The same computer can contain several product instances, so diagnosis must stay attached to the exact object that returned the HRESULT. The code is not interchangeable with a valid cache that is merely stale until refreshed.
Windows reports “The Software Licensing Service reported that the policy cache is invalid”.
What to collect first
| Different result | If the experiment instead proves “the local licensing platform detects modification of protected license state or components”, diagnose that condition separately rather than treating it as this HRESULT. |
Safe recovery direction
To correct this using supported mechanisms, preserve the policy source and cache events and use supported service/licensing recovery.
