When you try to update the Adobe Help application (also called the Community Help application), the following installation error occurs:
"The application could not be installed because the AIR file is damaged."
Delete the following directory:
Tip: To find this directory in Windows, copy the preceding phrase into the Windows Explorer file manager.
Mac OS: /[user name]/Library/Preferences/chc.4875E02D9FB21EE389F73B8D1702B320485DF8CE.1
As an extra precaution, Adobe recommends deleting the local, downloaded content at the following locations as well:
Windows : C:\Users\Public\Documents\Adobe\ (Help and PDF directories within)
Mac : \Users\Shared\Documents\Adobe (Help and PDF directories within)
The Adobe Help application is built and managed using the Adobe AIR framework. Because Adobe AIR has its own installation and uninstallation procedures, Adobe Help application updates are independent of the Creative Suite installers. There is no need to uninstall the entire Creative Suite or any associated product to resolve this issue.
