Ircnfutl is a command script that is used to read or update Prognosis configurations. As per support case, I believe the dificulties the command had at executing during the patch install was related t pending updates in windows requiring a restart.
The error during this particular patch install and your configuration combinations could be ignored (Just click ok). As per other email, this pending windows restart state also had effects on IIS and our webui loading too. The windows restart you did at that stage did help.
