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.

Yeah! I don’t know how you figured this out, but I was getting the same warning box but in Japanese. You were right, just clicking off and on a check box in System Preferences/International did the trick.
Thanks!

Had same problem attempting to install Air as mentioned here and in the comments below the installer downloads pages on Adobe.com. I miss read Adobe’s support instructions to uninstall and then try again and deleted the uninstaller. I was really stuck.
I started a case with Adobe technical support and was given this web page in Adobe’s first response to my case. I came here, followed the instructions and all is well. Very important, I went to the download area of Adobe.com again and successfully installed an update. I suggest everyone check for that too.
Thank you so much for all your help. I hope others find this and are helped too. P.S. I suggested to the Adobe tech that they post this in their support area and give you proper credit.
Good Luck all!

I can’t thank you enough. This is the weirdest thing I’ve ever seen but it did the trick.

Just wanted to let you all know we believe this problem has been addressed in the next release. It seems to occur only on a very small number of Mac OS systems, which is why we didn’t catch it before this release.
For those who are wondering about the strange error message in this case: The message was designed to be used when an AIR-based application is started on a machine on which the AIR runtime can’t be loaded, usually because AIR has been uninstalled. The installer also loads the runtime, but since it loads a copy of the runtime embedded in the installer, that load *should* never fail. When it does, however, it goes down the same error handling path and displays this incongruous message.

Great of you to address this thing here. Glad you guys at Adobe are listening to the blogosphere. Good PR policy.

Your documented solution worked perfectly. Its amazing what goes on in the world of software. Write once run everywhere is such a pipe dream.
Thanks for your post

I’m having ALOT of people report this issue when attempting to install my .air app. I’m glad to hear it’s fixed in the next release, it’s getting a bad rap, even though I’m totally passing the buck to Adobe in my email responses here, lol

It seems to be predominant in cases where the user has Logic installed, and waveburner.

Didn’t work on 10.4.11 on a G3 iBook Clamshell.
