I'm having endless frustrations with trying to install Adobe AIR on my Macbook. I'm running OS X 10.6 Snow Leopard.
After launching the Adobe AIR installer file, it takes a while before a window appears citing an error (see attached screenshot).
The problem is that there is only ONE account on my Macbook and it IS set as the admin account. I have double checked and triple checked that the account has admin priviliges.
Since the last few days have fallen over the holidays and it's the weekend now, I've been unable to reach Adobe technical support by phone. Please help in solving this. 
I just spent days going through this. I had tried everything, even logging is at the root (Systems Administrator). I ran the uninstaller I don't know how many times, I ran the command line prompts. I was getting pretty frustrated and a bit angry about the whole thing. Then I saw the suggestion to look at my log files:
/private/var/log/system.log
When I took a peek at the log file from the install I found something very interesting:
Jul 9 20:27:24 /Volumes/Adobe AIR 1/Adobe AIR Installer.app/Contents/MacOS/Adobe AIR Installer[1088]: error during install: [ErrorEvent type="error" bubbles=false cancelable=false eventPhase=2 text="Unhandled exception Error: Could not create directory /Applications/Adobe/Flash Player/AddIns/airappinstaller" errorID=3010]
So I went to the directory Applications and found there was an old text file called "Adobe". I renamed that text file, than ran the Adobe AIR installer and it WORKED!!!
So make sure you take a peek at the log files at:
/private/var/log/system.log
Thanks!
