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.
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 condition |
|---|---|
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 | Different condition: the IID/CID version is well formed but unsupported by the current Software Protection Platform. |
SL_E_CIDIID_INVALID_DATA_LENGTH | Different condition: 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
- Avoid reusing a CID produced for another IID, product key, or machine state.
- Avoid posting complete installation or confirmation identifiers in public logs.
Verification after the change
After remediation, 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.
