In V12, the program help can be received either from the Web or from the installation (with identical functionality). By default, the installed help is used.
[In the first versions of V12 (< SP4), by default, the Web-help has been used. (This does not affect PARTS4CAD, as it basically uses the Web-help.)]
Help installed on Server/Client
Of course the help files have to be explicitly installed. (If not yet done, they can be installed subsequently via installer anytime.)
In order to use the Web-help, in the
start.env, in CADENAS_APPSERVER variable, set the inethelp parameter with value 1.CADENAS_APPSERVER=https://servername.cadenas.internal?sslport=443&inethelp=1
The following matrix shows for which combinations of Inethelp value and Help installed which help is used.
