Tomcat proxy configuration for update check or license activation
The default configuration does not support the specification of a user for the proxy, i.e. for the proxy the attribute "noauth" needs to be defined for the Tomcat server. Therefore browse to the path: [iGrafx path]/apache-tomcat-7.0.42/bin/tomcat7w.exe and start the exe.
Add to the Options below the "Java" tab
DproxyHost=proxy.company.adsDproxyPort=8080
The port or the host might need to be changed appropriately.
