Answer
There is a known issue on KB4056898 that would directly affect our product:
https://support.microsoft.com/en-us/help/4056898/windows-81-update-kb4056898
The symptom is:
When calling CoInitializeSecurity, the call fails if passing RPC_C_IMP_LEVEL_NONE under certain conditions.
When calling CoInitializeSecurity, the call may fail if passing RPC_C_AUTHN_LEVEL_NONE as the authentication level. The error message that is returned on the failure is: STATUS_BAD_IMPERSONATION_LEVEL.
This issue is resolved in KB4057401, install the following hotfix on top of the security fix and see if the status engine now starts:
