Now that AIR 2 is finally official (WAHOO!), I can hopefully get my express install working. I can get an application to install through the badge install process IF AIR 2.0.2 is already installed on the system. What I can't get it to do, is do it all -- update to 2.0.2 and then install the application.
Are you getting some kind of error?
There was an issue with a previous version of the Flash Player that has been resolved in later release.
Can you please test the version of the Flash Player you are running here
and let us know what version you have?
If you are not seeing an error, can you provide some additional details about what appears to be going wrong?
