Hi Lesley,
The internet version just means it requires an internet connection to activate the licence once you add the serial code to the software.
We are selling the 2021 licence and i don't believe the licences we are offering have any upgrades due so if you wish to upgrade to the next years licence then a fee would be payable to Vectorworks.
Just to make you aware, we are now including the transfer fee payable to Vectorworks within the £1750+VAT. If this is still of interest please send us your details via a private message and we can prepare an invoice.
Kind regards
David
