Try uninstalling any existing instances of the license server from Control Panel, restart the computer and run the installation again. If you get the same error message - click the "Ignore" button on the lower-left side of the installer window.
After the installation has finished - navigate to http://localhost:30304 in your browser and check if you can access the license server menu.
If you still have problems after that it will be best to send us an e-mail at support@chaosgroup.com .
