Sometimes certain language files are missing from installed Adobe apps. An update fails when it can't locate all the appropriate files to update.
System optimizer applications often delete extra language files. If you use such applications regularly, adjust the settings so they don't affect your installed Adobe apps. If the language files are deleted again, you need to uninstall and reinstall your Adobe apps to restore the language files.
