Please see the "options for commands" section of this manual for general information about the use of macros for configuration.
This macro can be used to prevent the accidental use of VBSCRIPT or JSCRIPT if you have reasons for not wanting it (see script alerts).
To disable script generation by MAKEMSI add the text of the error message you'd like displayed as the contents of this macro. This will of course prevent certain MAKEMSI commands from fully or partially operating and force more work on the user.
The "DllCa-C" command could be used to allow users to create C/C++ based custom actions instead.
