After SU6 My EXE.xml file no longer automatically enables operation of my Honeycomb Bravo LEDs

Nope, the formatting is wrong, unless thats just from this form messing it up. Does yours have the

<Name></Name>     </Disabled></Disabled>  edit, yeah this form doesn't like <> in the lines lol

etc. After you copy and paste go in front of each line and put 4 spaces, this will put the text in a grey “code box”

from mine:

  <Launch.Addon>
    <Name>AFCBridge</Name>
    <Disabled>False</Disabled>
    <Path>X:\Your\Full\Path\AFC_Bridge\bin\AFC_Bridge.exe</Path>
  </Launch.Addon>

If it is correct, maybe some permissions issue? You could try moving it out of the community folder and see what happens. Cause you say FSUIPC works, but its not in the community folder…
