fails, because "type library not registered". And my

...confirmed. Just setting version(1.0) rather than
version(0.91) for the library statement in the IDL, and
rebuilding/registering the resulting .EXE, now lets it
work just fine with the late-bound VB example, and:

...with Python just as well.
It's more delicate to keep the tlib version at anything but
1.0 (the IDispatchImpl templates on each ATL class
definition would need explicit major/minor parameters),
while this is a 1-line fix and opens up R interfacing from
this is what I'd recommend.
