I mean that I restart fsuipc, splash screen showed up then disappears and that's all, not connected with MSFS
Now I launched MSFS and this time Fsuipc connected with MSFS, next exited Fsuipc as You adwised, then restart manually and the same as before, just showed up splash screen, disappears and not connected
From the moment the FSUIC splash screen showed up to the moment it went to the main menu state, it took 4.36 sec.
I use many addons, for example FS Realistic and what I noticed, when I restart manually , fsuipc splash screen showing up together with FS Realistic even though FS realistic is already running in the background, maybe that's the problem.
