Thank you very much for your attempt to help, as I mentioned, I don't like to install any software on my work computer or important documents that is not validated by Microsoft, so I cannot perform the test you mentioned as it requires the prior installation of DirectX non-Windows validated software. In any case, I have used some other RC emulator software without any issues. What is incredible is that for €100, they give you a large box with a small code inside, not a set of instructions, and of course, everything is in perfect English, as if Spanish didn't exist. It's almost the same as saying about Spektrum with WS2000, what's the least they could do is provide a way to check the device without having to load the tedious, invasive, and slow Steam software. What I want is a flight simulator, not to become a member of a platform that sells games and has difficulty finding the PLAY button for something I've already paid for. In the age of AI, it's not possible for something to be so complicated, and especially not so expensive when it lacks quality and support. What's evident in this chat is that users are providing support for free, wasting our valuable time. In summary, after wasting €150, I do not recommend anyone to purchase these two products, Spektrum WS2000 and RealFlight Evolution SW (I wonder where the evolution is?), and Horizon Hobby will never be the same for me. I feel completely frustrated and powerless. Many thanks to the marvelows people who try to help in this chat and who work for free to provide the services that the manufacturer does not provide. Greetings from Spain.
