There is more than one definition of the AIR 2.6 player. Only the first definition will be used.

If you're not trying to do anything fancy, then I wouldn't worry about it too much. However, if you're trying to overlay a newer version of AIR then you'll want to change some things.

I'm on mac so you may have to change the paths I give you to PC if you're on a PC.

Anyway, what's going on is that flash is confused on which xml file as actually for 2.6 because it found multiple files matching for AIR 2.6 in the <name> tag

Look in the folder $FLASH/Common/Configuration/Players/ and there should be a number of files specifying versions of AIR. If you are trying to overlay additional versions of AIR, you need to change for file to something like the example below.

[AdobeAIR3_1.xml]

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

<players>

  <player id="AdobeAIR3_1" version="14" asversion="3" minasversion="3">

    <name>AIR 3.1</name>

    <publishobject2 id="Air2_5" version="2.6" intversion="2.6"></publishobject2>

    <path platform="WIN">Air2_5.dll</path>

    <path platform="MAC">Air2_5.bundle</path>

    <playerDefinitionPath as2="$(UserConfig)/Classes/FP9;$(UserConfig)/Classes/FP8;$(UserConfig)/Classes/FP7" as3="$(AppConfig)/ActionScript 3.0/AIR3.1/airglobal.swc" />

    <!-- This item is used to indicate that some UI integrated within Flash should be enabled for this player.

    <feature name="multiScreenPublish" supported="false" />   

    <feature name="mobileDebug" supported="true" />

    <feature name="apolloPublish" supported="true" />

    <feature name="apolloTestMovie" supported="force"/>

    <feature name="useDefineFont4ForDeviceText"          supported="true" />

    <feature name="useDefineFont4ForEmbeddedFonts"       supported="true" />

    <feature name="textLayoutFramework"       supported="true" />

    <encodingPresets>

              <preset uuid="0c95a8ba-8b71-44d5-b269-8fd1cf89a6ed"  name="F4V - Same As Source (Flash 9.2 and Higher)" ext="f4v" default="true"/>

          </encodingPresets>

  </player>

</players>

You'll notice that the following values changed:

- <player> id: to AdobeAir3_1

- <player> version: to 14

- <name> to AIR 3.1

- <playerDefinitionPath> as3: path to where the NEW airglobal.swc is eg. $(AppConfig)/ActionScript 3.0/AIR3.1/airglobal.swc

Hopefully that helps.
