Installer logs for AIR 2 application and runtime installation

In AIR 2, installation logs are created by default. The file is named "Install.log" on Linux and Windows. The file is named "system.log" on Mac OS. This log file is cumulative, meaning that new log information is added at the end of the existing log file whenever an attempt, successful or unsuccessful, is made to install or update the AIR runtime or an AIR application. The size of the log file is limited to 0.5MB and will be truncated when exceeding this size.

The location of this file differs from platform to platform:

  • On Windows XP: C:\Documents and Settings\<username>\Local Settings\Application Data\Adobe\AIR\logs\Install.log
  • On Windows Vista/ Windows 7: C:\Users\<username>\Appdata\Local\Adobe\AIR\logs\Install.log
  • On Mac OS X: /private/var/log/system.log (console application)
  • On Linux: /home/<username>/.appdata/Adobe/AIR/Logs/Install.log

If you have difficulty installing an AIR or an AIR application, the information added to the log file can help the application developer pinpoint the source of the problem.
