In the [Help] section, you can change from the locally installed .chm to Web-based help.
[Help] UseWebHelp=No WebHelpUrl=http://www3.rocketsoftware.com/bluezone/help/v61
The default value is UseWebHelp=No which instructs BlueZone Desktop to use the locally installed .chm file.
UseWebHelp=Yes instructs BlueZone Desktop to use the Web-based HTML help. You must run setup.exe for this change to take affect.
