SL_REMAPPING_MDOLLAR_INVALID_ARGUMENT
The scope of SL_REMAPPING_MDOLLAR_INVALID_ARGUMENT, HRESULT 0x803FA07D, is Microsoft-hosted activation and product-key rule processing: the activation service rejected an argument in the activation request before applying business rules. In a hosted activation invalid argument incident, client API and request version should be captured before another retry changes state.
Evidence that can change the diagnosis
| Record | Why it matters |
|---|---|
| Primary record | Client API and request version; this is the shortest evidence path to the decision. |
| Object correlation | Keep the product, account, package, device, key, or API identity associated with the recorded identifiers and values beside the first timestamped result. |
| Neighboring-state control | Use a controlled comparison that tests whether this result occurs before NO_RULES_TO_ACTIVATE, which means a valid request reached business-rule selection; this separates the named condition from a nearby status. |
| Before/after result | Retain the outcome before and after the corrective action “remove optional fields one at a time without changing product identity”; keep the same identifiers until a schema-valid request reaches the intended activation rule and returns a product-specific outcome. |
Why this HRESULT is specific
The failing value can be a key field, product identifier, request option, locale, timestamp or structured payload element. The caller must retain the outbound request schema and identify the exact rejected field.
The decisive question is whether the primary record supports the reported condition that the activation service rejected an argument in the activation request before applying business rules. Keep evidence tied to the failing operation.
How to distinguish nearby failures
Do not merge neighboring statuses: This result occurs before NO_RULES_TO_ACTIVATE, which means a valid request reached business-rule selection. The hosted activation invalid argument diagnosis remains attributable only while the primary record and the affected identity stay fixed.
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 rejected an argument in the activation request before applying business rules, together with the code, UTC time, and the same identity fields.
- Change one prerequisite: Remove optional fields one at a time without changing product identity; 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 a schema-valid request reaches the intended activation rule and returns a product-specific outcome; if another HRESULT appears, diagnose it as a new boundary.
Evidence-preserving cautions
While investigating this result, do not treat every invalid argument as an invalid product key. That shortcut can replace or invalidate that evidence before the original decision is understood.
Verification
The incident is resolved only when a schema-valid request reaches the intended activation rule and returns a product-specific outcome. Confirm the result by repeating the exact operation that produced this result; maintenance success alone is insufficient.
