Flash Develop invalid namespace with AIR 14.0

Question

I'm using Flash Develop 4.6.2.5, and I cannot compile my app with AIR versions above 3.9.

I've tried with 4.0, 13.0 and 14.0

Packaging: dist\app.apk

project\application.xml: error 102:
Invalid namespace http://ns.adobe.com/air/application/14.0 APK setup creation

FAILED.

Here is all the procedures I've already did:

Answer 1

After some struggle here is the solution:

Switch the order of the PATH at SetupSDK.bat (line ~35):

Original:

:succeed
set PATH=%PATH%;%FLEX_SDK%\bin

Modified:

:succeed
set PATH=%FLEX_SDK%\bin;%PATH%

---

The problem should be related with something that I've installed in my system %PATH% which is having conflicts with something from %FLEX_SDK%, by switching the order you are forcing the packager to give preference to Flex SDK.
