Friedrich,

If I wanted to keep my own 'log' of the install progress, what would be a
suitable file in which to keep that?

INI?....

This would obviously be quite different info to SB's own uninstall log... (I
am planning to try to design an install that can continue after failure of
an included sub-program)
So I don't want to 'get in the way' of the sb file.
