AIR 2 creates installation logs by default in a file named Install.log (system.log for Mac OS). This log file is cumulative. That is, the log file is appended whenever an attempt is made to install or update the AIR Runtime/Application. The size of this log file can grow up to 0.5 MB. On exceeding this size, the Install.log file is overwritten.
