Our commercial (paid) extensions for Joomla! 3 are updated through the Joomla! Update System (trouble shooting, see here), which is additionally supported, customised and optimised by our proprietary online software. The 'manual update' option described below is included as well.
PLEASE CHECK! If your present install is not the latest version, it may not yet support the Joomla! Update System. You can check and update manually, see below.

Our Joomla! extensions are provided with a 'version check' link in the extension management screen (back-end, tab 'Description'). See the example below.
Click on the link and you will be taken to our website. Then follow the instructions on the screen.
