Many thanks Christian!
Many thanks for understanding what I really mean!
Yeah,
We do not have any server installation!
We have dongles for each user, as you guys know Vectorworks won't run with out that dongle.
So,
That is why we do not like this scanning, because we do not want to do changes to the Norton, we simply want to keep our network secure.
I hope nemetschek is going to do something about this problem!
Anyway,
I do not know if there are other ways of using Vectorworks in my country (EU), that also is possible that dealer has made some mistakes by seling us these dongles.
