Having a issue getting my PFC com (RS232) hardware working but it looks to be a software issue... I have installed FSUIPC.DLL and moved the PFCFSX.dll file to the modules folder that FSUIPC makes when it installs. When I start FSX after doing this it does recognize FSUIPC by asking if I want to use the add on. I say yes but it never asks about PFCFSX. When I start the simulator the only item under Add-Ons is FSUIPC. I tried completely deleting and re installing FSX and doing the whole installation process over, following it to a T but no avail. I'm stuck in the same spot. Any ideas? Opperating system is Windows 10 and FSX is FSX Steam. If this post isn't in the right spot, I apologize.
