TsuPath
InstallMate sets this variable to the installer's fully qualified file path. Note that this path may differ between the original installation (when the installer runs from its installation media) and subsequent repair or uninstall sessions (when the installer runs from its installed base).
Usage
You can refer to this variable as <TsuPath>. To retrieve parts of its path, for example its parent folder path or its file name, use runtime functions such as $fdir() and $fname().
