For the types of errors and how to diagnose them, see
Section 9.3.3, “Errors When Installing the InnoDB Plugin on
Microsoft Windows”.
Be especially careful that the plugin-load
line in the
option file does not get split across lines when you copy and paste from the README
or this manual, which can produce an “unrecognized option” error in the error log.
