Thank you Ratnesh
I tried but nothing the message is always the same...
The problem is like this (for me in win 7-64 obviously):
I thought: maybe Adobe Story installer try to find adobe air in the "program files" and not in "program file (x86)"
I tried to start the Adobe AIR Application Installer.exe (C:\Program Files (x86)\Common Files\Adobe AIR\Versions\1.0) and open the "AdobeStory.air".
Starting installation, good...What?!, Application already present!
I look on directory:
The uninstall procedure don't had deleted the directory "Adobe Story"!
After manual deleting all works fine...
