The information on this page refers to License Statistics v6.6 or newer, which introduced the License Statistics Manager, a tool that replaces direct editing of the xflicstat.cfg configuration file for Windows installations. If you are running an older version of License Statistics, see documentation for previous versions.
License Statistics configuration includes a port setting for the HTTP server used for viewing License Statistics output. This setting (WEBSERVER_PORT found under the "HTTP" section of the xflicstat.cfg file, or "Port" found in the Webserver tab of the License Statistics Manager), defaults to port 80 if SSL is disabled, or 443 if SSL is enabled. You should check the log file to ensure that the port is available for your site, and change this setting if needed.
For common problems with configuring web server ports and steps to resolve them, see Configuring web server ports.
