AIR is intended to be a versatile runtime environment, as it allows existing Flash, Actionscript or HTML and JavaScript code to be used to construct a more traditional desktop-like program. Adobe positions it as a browser-less runtime for rich Internet applications that can be deployed onto the desktop, rather than a fully-fledged application framework. The differences between each deployment paradigm provides both advantages and disadvantages. For example, a rich internet application deployed in a browser does not require installation, while one deployed with AIR requires the application be packaged, digitally signed, and installed to the user's local file system. However, this provides access to local storage and file systems, while browser-deployed applications are more limited in where and how data are accessed and stored.[7] In most cases, rich internet applications store users' data on their own servers, but the ability to consume and work with data on a user's local file system allows for greater flexibility.
Adobe AIR 1.1 was released on June 16, 2008, and provides support for building internationalized applications. Runtime installation dialogs were localized to Brazilian Portuguese, Chinese (Traditional and Simplified), French, German, Italian, Japanese, Korean, Russian and Spanish. In addition, version 1.1 includes support for Microsoft Windows XP Tablet PC Edition and 64-bit editions of Windows Vista Home Premium, Business, Ultimate, or Enterprise.[8]
I find the whole Iplayer thing a mess frankly. if I open the Iplayer desktop and go to look for a programme it offers me the streaming screen but when I click on download it say I need to install the desk top.
All I can suggest is from the command prompt navigate to the air directory CD\ etc (you may need to do a search to find it) and then type “AdobeAIRInstaller.exe -uninstall” and run it.
