SL_E_LICENSE_INVALID_ADDON_INFO
SL_E_LICENSE_INVALID_ADDON_INFO is HRESULT 0xC004E01A from local Windows Software Protection Platform. It means that the installed license contains invalid add-on relationship information. The practical shorthand local Software Protection license invalid add-on info is useful because it points to add-on license ID, parent dependency ID and package source as the first evidence to preserve.
Why this HRESULT is specific
The local platform evaluates a graph of product instances, licenses, policy and protected state. The returning object and earliest event determine whether the failure occurred while loading prerequisites, authorizing a right, changing service state or committing status.
Evidence that can change the diagnosis
| Neighboring-state control | Use a controlled comparison that tests whether a malformed add-on relationship differs from a valid add-on whose parent license is missing; this separates the named condition from a nearby status. |
| Before/after result | Retain the outcome before and after the corrective action “reinstall the authorized add-on license and its matching parent package”; keep the same identifiers until the original operation succeeds. |
Controlled troubleshooting sequence
- Preserve the first decision: Record the earliest event stating that the installed license contains invalid add-on relationship information, together with the code, UTC time, and the same identity fields.
- Change one prerequisite: Reinstall the authorized add-on license and its matching parent package; do not combine this with a store reset, key replacement, account removal, package reinstall, or unrelated repair.
- Repeat the user operation: Re-run the original operation and require that the original operation succeeds; if another HRESULT appears, diagnose it as a separate result.
How to distinguish nearby failures
The key comparison is this: A malformed add-on relationship differs from a valid add-on whose parent license is missing. A valid local Software Protection license invalid add-on info test keeps add-on license ID, parent dependency ID and package source attached to the same object and varies one supported prerequisite.
Evidence-preserving cautions
While investigating this result, do not delete Tokens. Dat or reinstall keys as a first response unless evidence identifies store damage or a key problem.
Verification
The incident is resolved only when the original operation succeeds.
