No worries, I managed to get the plugin installed.

The difficulty I have now, is that when I try to flow the twisted straight rod onto the donut, I can't seem to get it right. I appear to be picking the wrong curve.

In flow, it asks to pick the object to flow. I pick the twisted straight rod. It then says select the base curve or surface. I select the circle of the donut. It then says
select target curve near matching end. I select the profile of the straight rod and I get a weird shape.

Sorry about this...

Another question.. Is there a way to transform one object and get the same transformation in another?

Thanks very much Burrman.
