Hi all, every time I try to open vPilot - it displays an error message (error text below). I have tried to look it up, read dozens topics of this forum, FAQs and Troubleshooting Guide, but no answer to solve this problem. All things I do: 

  • run vPilot as administrator 
  • reinstall vPilot
  • check microphone permission (Win10) - Allow apps to access this microphone 
  • check the last version of .NET Framework 4.8 has been installed
  • check Windows Media Feature Pack has been installed
  • change the input/output from built-in Realtek to a) bluetooth headset b) USB headset Sennheiser

Nothing helps ... Could you please help?

Try physically removing each capture device one by one. One of your microphones may not be initialising correctly
