When running tlinstaller with an already up-to-date installation in place and you arrive at the "This system already has an up to date installation of ThinLinc"-page, there is no clear way of exiting the installer. On this page, the user is shown three buttons, none of which are really applicable to just closing the installer: "Cancel", "Back", and "Forward" (greyed out) The current way of closing the installer is by clicking "Cancel" and then choosing to "Abort" the installation in the succeeding dialog. This is somewhat confusing as we are neither canceling nor aborting anything at this stage.
