ConfirmConnect - Cannot set appSetting MapInfo.Engine.Session.State to HttpSessionState

Product Feature: ConfirmConnect - Installation/Upgrade


 
Error occured in Confirm v3.04.1. The problem seems to be originating from the web.config file. A solution was found to use a web.config file from an older v3 version, which fixed the error. be sure to install every prerequisite for Confirm too.
