HRESULT 0xC004F01E is exposed as SL_E_DATATYPE_MISMATCHED by the local Software Protection Platform. The code says more than the friendly message: the caller supplies a value whose type differs from the type declared by the license property.
Windows reports “The Software Licensing Service determined that the input data type does not match the data type in the license”.
From input to HRESULT
Stage
Role
Product instance
Application ID and Activation ID identify the exact licensed object.
License inputs
Packages, dependencies, signatures and policies feeding this result are loaded for that object.
Requested transition
Record the exact licensing operation that returned this HRESULT.
Commit or status
Do not infer the intended licensing state from outputs produced by the failed operation.
What the constant itself tells you
Signal
Interpretation
Family
The code comes from Software Protection Platform; correlate it with one product object rather than the computer as a whole.
Object
Two independently identified objects or values do not agree.
Operation
Use the exact HRESULT and first failing operation before attempting a broad activation reset.
State
Its HRESULT severity is failure; later status messages can describe only the resulting state.
Evidence to keep before remediation
Evidence
Question answered
Application ID, Activation ID and product name
Which Application ID and Activation ID returned the code?
LicenseStatus, LicenseStatusReason and grace values
Was the failure during package load, policy evaluation, authorization or service maintenance?
first API/slmgr method and earliest Security-SPP event
Is the named object absent, invalid, mismatched, duplicated or in the wrong lifecycle state?
property key, expected type and supplied type
Can caller identity and elevation be captured before changing state?
caller identity and elevation
Which account and token performed the operation, and was the required elevation present?
Code-specific distinction
Does the evidence support “record property name, expected type and supplied type and correct the API caller” rather than a correctly typed property that is missing or read-only?
Work from identity to cause
Record 0xC004F01E, UTC time, caller and the first method or server request that returned it.
Capture first API/slmgr method and earliest Security-SPP event.
Before remediation, confirm that the failure is not instead the neighboring condition: a correctly typed property that is missing or read-only.
the cryptographic signature on a license or associated artifact does not verify
SL_E_INVALID_LICENSE
the selected license object fails general structural or semantic validation
SL_E_DECRYPTION_LICENSES_NOT_AVAILABLE
the licenses required to decrypt or interpret protected licensing data are absent
A focused reproduction for this exact result
Control
Design
Failing fixture
Automation sends text where the license schema requires an integer or binary value.
Single variable
Change only property identity, declared type and supplied value.
Positive control
A schema-defined property accepts a value of the declared type.
Different result
If the experiment instead proves “the cryptographic signature on a license or associated artifact does not verify”, diagnose that condition separately rather than treating it as this HRESULT.
What successful remediation must prove
A supported correction is to record property name, expected type and supplied type and correct the API caller.
Changes that make this code harder to diagnose
Avoid force-deleting policy, plug-in or license files while sppsvc owns them.
Avoid using rearm or key replacement as a universal package/policy repair.
Avoid copying license packages or protected stores from another computer.
