Greetings to all. I would like to request your technical assistance. I'll tell you a little bit, I bought my 737 overhead from vrinsight, my question is the following, the idea of buying it was to use it in my 2004 flight simulator, it is the configuration of my current cabin, until today that I send this message I can't get it to work in said simulator, it took me months to get it to work in flight simulator x, that's where it works, could you advise me on how to get it to work and what I need for it to be functional in fs2004, I installed according to my knowledge the drivers for vrinsight, the free fsuipc 3 from the official page and the pmdg 737, when starting the interface it says "fsuipc not found" and from there I never managed to use it, hopefully with your experience you have some idea of how to achieve it. Or if someone managed to configure it in 2004 advise me on what I need. Thank you very much.
