AdobeAIR Runtime Redistribution exit code 9

Hi there,

Anyone see the exit code "9" for the AdobeAIR using the bundle runtime installer? This only seems to happen on Mac OSX

Steps to replicate the issue:
1. On a Mac, uninstall Adobe AIR 1.5.0 in /Application/Utilties/
2. Run the bundle runtime installer, with -silent option
3. .airinstall.log reports,
App installer failed; exit code 9

Thanks in advance, really appreciate for any assistance.

Thanks,
Calebmei
