On Mac OS X: /Users/[user name]/Library/Application Support/Adobe/AAMUpdater
Where [user name] is the user name with which you are logged in to the system.
2. Rename the 1.0 folder to 1.0_old.
For example, navigate to the AAMUpdater folder on your computer and change the name of the folder 1.0 to 1.0_old.

Mac OS X: In the Finder, select Go > Go to Folder. In the Go To Folder dialog box, type ~/Library/Application Support/Adobe/AAMUpdater and click Go.
