It work but without sounds

Add this:

  <Launch.Addon>
    <Name>Captain Sim Sound</Name>
    <Disabled>False</Disabled>
    <ManualLoad>False</ManualLoad>
    <Path>Captain_Sim\bin\cs.sound.dll</Path>
  </Launch.Addon>


Make sure that those lines are between the lines

<?xml version="1.0" encoding="UTF-8"?>

<SimBase.Document Type="AceXML" version="3,0" id="dll">

and

</SimBase.Document>

Like this:

<?xml version="1.0" encoding="UTF-8"?>

<SimBase.Document Type="AceXML" version="3,0" id="dll">
  <Launch.Addon>
    <Name>Captain Sim Sound</Name>
    <Disabled>False</Disabled>
    <ManualLoad>False</ManualLoad>
    <Path>Captain_Sim\bin\cs.sound.dll</Path>
  </Launch.Addon>
</SimBase.Document>

I think you can find the dll.xml file in here: C:\ProgramData\Lockheed Martin\Prepar3D v5, but I also have one in C:\Users\<Username>\AppData\Roaming\Lockheed Martin\Prepar3D v5
I think that the one in the AppData folder was added by the Captain Sim 767 Captain II for P3D4/5 installer.
