SL_E_CIDIID_INVALID_VERSION
What this result narrows down
SL_E_CIDIID_INVALID_VERSION identifies a specific point in offline IID/CID activation: the offline activation exchange in which an Installation ID is generated for one activation context and a Confirmation ID is returned for that same context. Its diagnostic consequence is that the local decoder recognizes an IID/CID envelope but its version field is invalid.
This result is HRESULT 0xC004F02D. Pair it with the selected product/Activation ID and operation name so later logs do not attribute an add-on, edition, or volume-license result to the base Windows product.
Checks in the order that matters
- Select the exact licensing product or Activation ID that returned this result; do not rely only on the first line of
slmgr /dlv. - Confirm the mechanism in use: the offline activation exchange in which an Installation ID is generated for one activation context and a Confirmation ID is returned for that same context.
- Prove the code-specific condition by collecting: capture OS/build, Software Protection Platform version, identifier source, and the version reported by the offline-activation workflow.
- Apply the distinction “an invalid version is not the same as a recognized version that this installation does not support” before choosing a key, network, certificate, firmware, time, or entitlement repair.
- Change one decisive precondition, rerun one activation/evaluation operation, and verify the resulting LicenseStatus and LicenseStatusReason.
The surrounding licensing model prevents two common misdiagnoses. Formatting errors, unsupported versions, mismatched IDs, and a failure to save a valid CID occur at different points and should not be merged into one “telephone activation failed” message. The Installation ID must be obtained before the Confirmation ID is deposited; the returned CID is tied to the activation context represented by that IID.
Data that identifies the actual cause
Capture OS/build, Software Protection Platform version, identifier source, and the version reported by the offline-activation workflow. Before changing the system, add the following context:
- Product identity: Activation ID selected for /dti and /atp.
- Activation context: IID and CID length/version without publishing the complete identifiers.
- State at failure: partial product key and edition/channel.
- Correlation evidence: hardware or environment change between IID generation and CID deposit.
- Change history: exact slmgr or API operation and Software Protection event.
When investigating this result, protect secrets while collecting evidence. Full product keys, complete IID/CID values, private keys, PINs, challenge blobs, account credentials, and unredacted certificate material do not belong in public tickets. Partial keys, hashes, thumbprints, IDs, timestamps, and state transitions are normally enough to correlate the failure.
The diagnostic fork is precise: an invalid version is not the same as a recognized version that this installation does not support. A broad instruction to “try another key” or “check the Internet” would discard the more specific condition already established by the code.
Recommended handling
Resolve this code at its producing layer: generate a new IID on the target installation and use a CID issued for that current request. A successful command is not enough by itself; verify the stored licensing state and any renewal, validity, or binding data affected by the operation.
Representative failure: A saved CID from an earlier activation technology is applied to a newer installation.
Nearby results that require a different response
| Result | Different boundary |
|---|---|
SL_E_CIDIID_INVALID_DATA | Relative to this result: the local Software Protection Platform rejects the supplied offline activation data as structurally invalid. |
SL_E_CIDIID_VERSION_NOT_SUPPORTED | Relative to it: the IID/CID version is well formed but unsupported by the current Software Protection Platform. |
SL_E_CIDIID_INVALID_DATA_LENGTH | Relative to it: the local deposit operation receives an IID/CID payload with the wrong total encoded length. |
Choosing remediation by the symbolic code prevents an entitlement problem from being treated as transport failure, or a state-transition result from being treated as a bad product key.
Actions that usually make this harder to diagnose
- While diagnosing it, avoid reusing a CID produced for another IID, product key, or machine state.
- Avoid posting complete installation or confirmation identifiers in public logs.
- Do not delete licensing stores, edit signed license files, alter firmware markers, bypass certificate checks, or use unofficial activation tools. During investigation, those actions can create a second integrity problem and destroy the evidence needed to repair the legitimate license.
Verification after the change
After remediating it, repeat the original operation rather than relying on the absence of a notification banner. Confirm that it is no longer produced and that the intended product instance reports the expected durable licensing state.
