Hi friends.
Editing the dll.xml file helped me

For example, I attach a screenshot.

The file itself is located c: \ users \ ... \ AppData \ roaming \ microsoft \ fsx \

The main thing is to specify the correct path in the dll to your simulator and exclude all spaces!

I have it like this:


  <Launch.Addon>
    <Name>Captain Sim Sound</Name>
    <Disabled>False</Disabled>
    <ManualLoad>False</ManualLoad>
    <Path>C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\Captain_Sim\bin\cs.sound.dll</Path>
  </Launch.Addon>


  Good luck!
  I hope this helps you guys!
