An upgrade needs to be purchased for each channel required.
IMPORTANT NOTE WHEN YOU UPGRADE!
Always indicate in the comments field on your order the serial number or dongle serial number that you have and that needs to be upgraded. If you don't we'll have to mail you back to ask for it anyway ;-)
HOW TO UPGRADE ?
If your current license is a Serial Number,
You will receive an upgrade serial number that you will add to the list of serial numbers in the "License" window and activate it, just as a "Master Serial Number" (the one that you received when you first ordered. This means that you will always have to have the 2 Serial Numbers activated.
If your current license is a Serial Number but you want to upgrade to a dongle,
Additionally to your upgrade, just order a dongle (one per computer) and upon order, in the comments field, indicate the serial number it should replace. The upgrade procedure can be found here.
If your current license is on a Dongle (Grey with the Softron logo),
We will send you an upgrade file for the dongle serial number that you have indicated in the comments field when placing your order. The upgrade procedure can be found here.
For more information on the activation/deactivation process or the dongles, you should have check the Knowledge Base about our licenses available on the Softron Support Desk.
