Current versions are. But, if you bought CS6 outright when Adobe switched to a cloud subscription model then CS6 is not going to work any longer (it's 32 bit).

That's the boat I am in. I can afford their cloud subscription but out of principle I will try their main competitor first (Affinity: $50 one time purchase). I will try running it in a VM second. Only if neither of those solutions are satisfactory will I pay a monthly fee for software that I use very little.
