The conceptQS application requires the installation of WCF.NET components.
This is checked as part of the pre-install checks that are carried out by the installer from version 5.3.9 onwards.
If you have installed the conceptQS using an older version of the installer, then this will not have been checked, and you will receive the errors:
“The remote server returned an error (405) method not allowed”
You will need to enable the WCF.NET component in Server Manager.
