    ; This script shows how to use IUnknown based COM Automation objects.

    ; REQUIRES UNICODE INNO SETUP!
    ;
    ; Note: some unneeded interface functions which had special types have been     replaced
    ; by dummies to avoid having to define those types. Do not remove these     dummies as
    ; that would change the function indices which is bad. Also, not all     function
    ; protoypes have been tested, only those used by this example.
