800736B2 ERROR_SXS_INVALID_ACTCTXDATA_FORMAT
The application binding data format is invalid.
Are you sure that you disabled all of KIS' services, processes, and
firewall ? Did you enable the native Vista firewall ?
You could try running the System Update Readiness Tool to see if that
resolves the error:
