SL_REMAPPING_MDOLLAR_INVALID_BINDING
Within Microsoft-hosted activation and product-key rule processing SL_REMAPPING_MDOLLAR_INVALID_BINDING (0x803FA066) reports that the activation service found that the product key binding does not match the product or device context presented by the request. Treat it as the hosted activation invalid binding condition and start with partial key and product key ID, not with the final dialog text.
Why this HRESULT is specific
Activation data binds a key or entitlement to product metadata and, in some channels, a device or manufacturing association. The service rejected that relationship before granting activation.
The decisive question is whether the recorded evidence supports the reported condition that the activation service found that the product key binding does not match the product or device context presented by the request. Keep evidence tied to the failing operation.
How to distinguish nearby failures
Nearby condition: It is narrower than INVALID_PRODUCT_DATA: the decisive issue is the relationship between otherwise identifiable objects. Hold partial key and product key ID constant while changing only the prerequisite described.
Evidence that can change the diagnosis
- Primary record: partial key and product key ID.
- Object correlation: keep the product, account, package, device, key, or API identity associated with partial key and product key ID beside the first timestamped result.
- Neighboring-state control: use a controlled comparison that tests whether it is narrower than INVALID_PRODUCT_DATA: the decisive issue is the relationship between otherwise identifiable objects; this separates the named condition from a nearby status.
- Before/after result: retain the outcome before and after the corrective action “for OEM scenarios, validate the firmware marker and image edition together”; keep the same identifiers until the corrected product and device context produces a valid binding.
Controlled troubleshooting sequence
- Locate the exact object: Use the primary record to identify the transaction or licensed object that actually returned this result.
- Preserve the first decision: Record the earliest event stating that the activation service found that the product key binding does not match the product or device context presented by the request, together with the code, UTC time, and the same identity fields.
- Change one prerequisite: For OEM scenarios, validate the firmware marker and image edition together; 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 corrected product and device context produces a valid binding; if another HRESULT appears, diagnose it as a new boundary.
Evidence-preserving cautions
While investigating this result, do not copy licensing stores from another machine; that creates another binding mismatch and destroys provenance. That shortcut can replace or invalidate that evidence before the original decision is understood.
Verification
The incident is resolved only when the corrected product and device context produces a valid binding. Confirm the result by repeating the exact operation that produced this result; maintenance success alone is insufficient.
