Can't run any android project from qt creator and adt-20140321

On a workstation I installed Qt 5.2.1, adt-bundle-windows-x86_64-20140321,, android-ndk-r9d, apache-ant-1.9.3.
Run Qt Creator and set up all the directories. Created a couple of devices.

Trying to run an android application appears the form from which decide which device to use but they are ALL listed as incompatible.

On another workstation that had previous versions of qt, ndk, sdk and ant and everything was working, I updated to these versions and I got the exact some problem.

In both cases I also got these messages in “General message” panel

Project ERROR: You need to set the ANDROID_NDK_ROOT environment variable to point to your Android NDK.
