What does HRESULT 0x803FA068 (SL_REMAPPING_MDOLLAR_INVALID_PRODUCT_KEY) mean?

SL_REMAPPING_MDOLLAR_INVALID_PRODUCT_KEY

Within Microsoft-hosted activation and product-key rule processing SL_REMAPPING_MDOLLAR_INVALID_PRODUCT_KEY (0x803FA068) reports that the activation service could not accept the submitted value as a valid product key. Treat it as the hosted activation invalid product key condition and start with partial key and input source, not with the final dialog text.

Why this HRESULT is specific

The key may fail structural checks, product lookup, channel validation or associated product data checks. Preserve the exact stage rather than reducing the result to a generic connectivity failure.

Evidence that can change the diagnosis

• Primary record: partial key and input source.

How to distinguish nearby failures

Nearby condition: INVALID_PRODUCT_KEY is broader than INVALID_PRODUCT_KEY_LENGTH and should not be diagnosed as a length problem unless the input evidence proves it. Hold partial key and input source constant while changing only the prerequisite described.

Controlled troubleshooting sequence

1. Record the earliest event stating that the activation service could not accept the submitted value as a valid product key, together with the code, UTC time, and the same identity fields.
2. Change one prerequisite: Check whether deployment automation supplied a placeholder or setup key; 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 intended key is accepted; if another HRESULT appears, diagnose it as a separate result.

Evidence-preserving cautions

While investigating this result, do not publish the full key or test it against unrelated machines.

Verification

The incident is resolved only when the intended key is accepted.
