I downloaded the trial version of Flash Builder, made an app, and it worked. I was going to start doing some less trivial tests, and realized that I was using 1.5.2. So I went through the step to upgrade to 2.0.
I'm using Flex 4.0 (build 10485), and set xmlns="http://ns.adobe.com/air/application/2.0beta". Run the debug, and there's no problem at all. When I try to install it, I get the error "Sorry an error has occured. This application requires an update to Adobe AIR that is not available for your system. Please view the system requirements for Adobe AIR and update your system accordingly."
Here is the list of requirements that I was sent to: http://www.adobe.com/products/air/systemreqs/
I looked at my system requirements and I have more than a Pentium III. I have more than 512MB of RAM. I am also running Windows 7.
I don't know what I am doing wrong. This is my first experience with Flash Builder. When you reply, feel free to treat me like I don't know anything...because right now, I only know how to create a panel that says, "Hello World".
Thanks for the interest in AIR 2. A couple of things I'd like to suggest.
First, if you're using the GM AIR 2 SDK (and I'd like to suggest you do), please change the namespace to xmlns="http://ns.adobe.com/air/application/2.0". You'll run into error's if you try and run an application built with a beta SDK with our released runtime.
Next, once your app is installed, please make sure you've installed the AIR 2.0.2 Runtime.
This should hopefully get you going. Please let me know if you continue to run into problems.
Ah. I didn't realize that I was supposed to put the contents of the AIR SDK in the folder of the Flex SDK.
I see why Adobe offers 60 days for the trial.
Thanks a bunch.
