Every time we buy a piece of hardware we get a copy of Resolve Studio. Are each of these copies individual licences? And for each licence, is there a limited number of machines you can install Resolve on?
Some cameras come with licenses for the Studio version, but not the other hardware. A license key can be activated on two machines at the same time and can be moved to other machines.
Yes, two dongles equals two licenses. If you want you may be able to convert the dongles to activation keys if you bought them before Resolve 14 was released. More info here.
