tlclient.cgi is an optional component and is only installed if a apache httpd server is found on the system. Even if it is installed, we can't be sure that it's present on the $thisserver hostname, at the /thinlinc/ path, on the https port.
There are also other options available, like integrating tlclient.cgi functionality directly in tlwebadm, or using the HTML client.
It also assumes that tlclient.cgi is available on the default port.
