First thing you should know – all updates are free during 6 months after your purchase, you may update as many times as you want within this period of time.
If you like you can prolong update period by purchasing Update Service for 6, 12 or 24 months – see product order page.
The best way to update is to use an automated notification that Store Manager shows (green arrow at the right top corner of Store Manager application). Simply click on it to download newer version.
Store Manager checks for a newer version every time it is started.
Also you can find download links of recent versions at: http://license.emagicone.com
You may install the new version over your existing one, all connection settings and other information will not be changed. If you uninstall your current version and then install newer you may need to register it again.
