SL_E_INVALID_OFFLINE_BLOB

Where this result is produced

SL_E_INVALID_OFFLINE_BLOB is HRESULT 0xC004C329. It belongs to Genuine Validation. Its narrow boundary is: the offline validation package is malformed or cannot be authenticated as the expected evidence bundle.

Windows reports “Genuine Validation determined the offline data blob is invalid”.

Objects and state transitions

Different resultIf the experiment instead proves “the client token supplied to Genuine Validation cannot be authenticated or parsed as the expected token”, diagnose that condition separately rather than treating it as this HRESULT.

Recovery without broad resets

To correct this using supported mechanisms, regenerate the offline bundle on the intended device and avoid copy/paste transformations.

Changes that make this code harder to diagnose

  • Avoid hand-editing signed blobs, protected files or firmware tables.
  • Avoid using unofficial activation patches during integrity investigation.
  • Avoid rebuilding stores before preserving hashes and event history.
