Hello @divya_1993
The issue is not Adobe AIR per say. But Adobe CS5.5 which has a packaged AIR inside the package. CS5.5 has been downloaded from Adobe site (and re-downloaded 2 weeks ago and still same issue). When installing CS5.5 there is AIR applications INSIDE 5.5 installation which fails because their sign in is old. Now how can I fix this? As these are Adobe signed applications in CS 5.5.
