Hello Aledin,
ArtRage Vitae is ArtRage 7 and is now distributed only via the Mac App Store or the Microsoft Store.
My current understanding is that ArtRage 6 is still to be maintained but not developed further.
In much the same way as they have for past obsolete versions of; AR3, 4, & 5.
Andy dose say in his post here that they will still offer support for AR6: https://forums.artrage.com/showthrea...599#post538599
