Hi,
Once you download the version of your choice from Find and download archived versions of Adobe AIR SDK , what is the exact problem that you are facing? Does it not get download.? does it get downloaded but does not get installed? dou you see any error message?
Or
"Go to Adobe AIR Installer in downloads, right click and go to Properties, go down to Security and click on Unblock. All being well, it should work then" The 'Unblock' is NOT under Security...it is under the General tab in the lower half.
Thanks!
