What does HRESULT 0xC004C4AC (SL_E_INVALID_TOKEN_DATA) mean?

SL_E_INVALID_TOKEN_DATA

0xC004C4AC is represented by SL_E_INVALID_TOKEN_DATA. In Windows genuine validation and Software Protection integrity checks the specific outcome is that genuine validation rejected token-activation data as structurally or semantically invalid. The phrase genuine validation invalid token data narrows the first diagnostic record to token license identifier and version.

Why this HRESULT is specific

Token activation grants and records are structured licensing objects. The code identifies invalid token data before the requested entitlement can be trusted.

Controlled troubleshooting sequence

1. Record the earliest event stating that genuine validation rejected token-activation data as structurally or semantically invalid, together with the code, UTC time, and the same identity fields.
2. Change one prerequisite: Look for truncation, unsupported conversion, or stale provisioning output; do not combine this with a store reset, key replacement, account removal, package reinstall, or unrelated repair.
3. Repeat the user operation: Re-run the original operation and require that the correct token data is accepted and the expected license grant appears; if another HRESULT appears, diagnose it as a separate result.

How to distinguish nearby failures

The key comparison is this: It is distinct from a missing token activation license and from a valid token whose policy denies use. A valid genuine validation invalid token data test keeps token license identifier and version attached to the same object and varies one supported prerequisite.

Evidence that can change the diagnosis

• Primary record: token license identifier and version.

Evidence-preserving cautions

While investigating this result, do not edit token data or import grants from another device.

Verification

The incident is resolved only when the correct token data is accepted and the expected license grant appears.
