Keep your LSS software updated

Please note that LSS will attempt to check for program updates automatically. A Windows service will run on your computer and check when you log into your computer and at around 12:00pm (local time) every day, when you’re logged-in. If it finds an update to LSS it will display a message (see the images above right). Clicking on this message will initiate the update process. If your IT systems block such activity you will need to keep checking our website for the latest version of LSS, or subscribe to our e-bulletins for monthly news on product developments.

Download previous versions of LSS

If you are already using LSS v10, but for whatever reason want to reinstall a previous version, then you can do so from here.

Note that unless you choose a different folder to install to, the following versions will overwrite your existing LSS v10 installation (but NEVER your data or settings). Once downloaded, unzip into a new folder and then run ‘MTSL.Setup.exe’. On the first dialogue you will be able to select the install folder.

Download v10.01.24
