I unregistered the vbscript .dll and attempted to run an install I'm working on and it immediately hit a fatal error.  The reason was to test if vbscript needs to be installed.  Does Wise require that vbscript be installed in order to run an installation?  The installation being tested does run a vbscript from a custom action, but not until later in the install.  This error was instant.

A related question:  I need to run a vbscript that uses ADO.  How can I make the install add ADO as a prerequisite?

Thanks,
