If the numbers differ, proceed with the download and update.
- To update you module: uninstall it and delete it from the PrestaShop administration, then copy the "/autoupgrade" folder from the module's archive (that you have downloaded from the Addons website) to the "/modules" folder of your installation of PrestaShop. Finally, install the module from the administration.
- PrestaShop 1.5 and later versions: PrestaShop will automatically check the Addons site for new versions of your modules. If a new version is available, it will present display a new button "Upgrade!" button next to the "Install/Uninstall" button. Click to have PrestaShop download and update the module for you.
