When trying to install Adobe AIR on my Mac running 10.5.4, I was getting this annoying message:

Error: Adobe AIR Installer requires Adobe AIR to be installed. What?
This application requires Adobe AIR to function. Please download the latest version of the runtime from http://www.adobe.com/go/getair, then launch the application again.
Which is weird because why would Adobe AIR require Adobe AIR to install? Isn’t that like… impossible?
I found the solution!
- Open System Preferences.
- Click on International.
- Click on Edit List
- Check Or Uncheck a Language (In other words, change something)
- Hit OK to save the changes
- Adobe AIR will now install!

- For Adobe AIR Installation, open System Preferences and click International



OSX Adobe AIR Installer Works Now!

Hey, just wanted to let you know. I was having problems installing AIR on my G4 powermac running 10.4.11, and getting NO error message (“bus error” if you opened it up through terminal) and this seemed to also fix my problem.
