For Windows and Mac, yes. V1 was very polished when I used it back in the day, I assume V2 is the same. For Linux, fuck no. They don’t care one bit about that OS.

I tried it with bottles. It installed fine after manually installing dotnet 4.8, but I couldn’t get Affinity Photo itself to run, even after extensive tweaks. All I get is an exception without any description in the terminal output.
