SL_E_MISMATCHED_SECURITY_PROCESSOR
The stage that stopped
SL_E_MISMATCHED_SECURITY_PROCESSOR is HRESULT 0xC004F00E. It belongs to the local Software Protection Platform. Its narrow boundary is: the license targets a different security-processor implementation or version than the one running.
Windows reports “The Software Licensing Service determined that the license could not be used by the current version of the security processor component”.
Evidence that avoids a false diagnosis
| whether a clean reboot reproduces the result without modifying state | Does the evidence support “align the signed license package and Windows servicing level; do not replace security components manually” rather than a general package-version mismatch unrelated to protected evaluation? |
Diagnostic sequence
- Record
0xC004F00E, 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 general package-version mismatch unrelated to protected evaluation.

cscript %windir%\system32\slmgr.vbs /dlv

| Result | Different condition |
|---|---|
SL_E_NO_PID_CONFIG_DATA | product-identification configuration needed to interpret a product key or Product ID is absent |
SL_E_LICENSE_FILE_NOT_INSTALLED | the expected license file is not installed in the local licensing repository |
SL_E_MISMATCHED_APPID | the license Application ID does not match the application/product object requesting it |
A focused reproduction for this exact result
| Control | Design |
|---|---|
| Failing fixture | A license package from another Windows generation is installed. |
| Single variable | Change only the two identities named by the HRESULT while all other state remains fixed. |
| Positive control | The matching pair is accepted and the mismatched control reproduces the failure. |
| Different result | If the experiment instead proves “product-identification configuration needed to interpret a product key or Product ID is absent”, diagnose that condition separately rather than treating it as this HRESULT. |
Fix the prerequisite, then verify
To correct this using supported mechanisms, align the signed license package and Windows servicing level; do not replace security components manually.
