Just like since X3.
Only difference right now is Cakewalk has a "offline" method where you could install and authorize an offline machine but you still had to have a online machine to get the code. At this point Bandlab is 100% on line install.. but that's more or less the same as 90% of the software I install. It's why Laptops don't come with DVD drives anymore. Everything is a download.
Bandlab is no different than most software. Once it's installed you can chose to disable your internet.
