SL_E_PRODUCT_UNIQUENESS_GROUP_ID_INVALID
Where the failure occurs in Software Protection Platform
SL_E_PRODUCT_UNIQUENESS_GROUP_ID_INVALID (0xC004E021) is emitted by license evaluation, policy and machine-binding state. It marks a specific point inside the rules engine that combines installed licenses, machine context, hardware identity, secure-store identity, policy values and current operation state: genuine-state information contains a product uniqueness-group identity inconsistent with the license context.
This distinction matters because this is product identity consistency, not malformed GUID syntax alone. A later “not licensed” state should not replace the first exact HRESULT in logs.
Where it sits in the licensing pipeline
Evaluation results should be tied to the exact licensing product instance; a computer normally exposes several products and add-ons with independent states. To verify this, record group ID, product/Activation ID, license package source and dependency chain.
Policy mismatch, hardware-data failure, invalid context and an already-running activation are distinct from a rejected key or unreachable activation server.
Evidence worth preserving
- LicenseStatus, LicenseStatusReason and concurrent operation state
- Application ID and Activation ID
- license package and policy generation
- hardware ID inputs and recent hardware/firmware changes
- secure-store ID, hashes and rule identifiers
From HRESULT to a verified cause
- Use read-only inspection first: record group ID, product/Activation ID, license package source and dependency chain.
Related codes with different remedies
| Result | Different condition |
|---|---|
SL_E_POLICY_OTHERINFO_MISMATCH | Compared with this result, a policy value disagrees with the corresponding value embedded in the license OtherInfo data. |
SL_E_SECURE_STORE_ID_MISMATCH | Compared with this result, the secure-store identifier recorded in the license does not match the active machine store. |
SL_E_INVALID_RULESET_RULE | Compared with it, a notification or licensing ruleset contains an invalid rule definition. |
Correcting the producing condition
Restore the correct genuine-information/license package for the installed product.
Representative case: An edition-mismatched package introduces a uniqueness-group ID belonging to another product family.
Actions that usually destroy useful evidence
- Do not reset the entire licensing store for a single policy or concurrency result.
- Do not change several inputs at once before identifying the rule, hash, context or operation that failed.
