    HTMLHelp =Y, Error message: "Action cancelled"

    • Article Type: General
    • Product: Aleph
    • Product Version: 18.01

    After switching to the setting "HTMLHelp=Y" in alephcom.ini it is not possible anymore to view any help files. A message "Action cancelled" is displayed instead of the help topic.

    This happens if the Aleph help files are located on a network drive. It is not a problem of Aleph, but of the security settings of Microsoft Internet Explorer. In order to see the help files, you need to add the following key to the registry:


    Here you assign a "MaxAllowedZone" between 0 and 4. While "0" blocks any reading access to the files, "4" permits every access. The setting "1" should be sufficient for paths within a local intranet.
