QTR-Quadtone RIP

I've used QTR on and off over recent years, but I've never tried to
linearise or create profiles, as I didn't have access to an I1 Photo.
 I now have one, and also a new R2400, and am about to begin.

I promise not to ask too many noob questions and will search the
archives.  But I notice a recent post to the effect that the
documentation needs some updating, so I may need to ask a few questions.

First Question: I haven't used the i1 for printer profiling yet, and
so this may be largely a question of ignorance about its software.  Am
I correct in reading that the latest version of i1 Match (3.6.2) still
will not read the step wedge in order to create the data for
linearising?  Is it still the case, as stated in the
Eye-One-ReadMe.pdf, that I'll need to download a demo version of
ProfileMaker 5, and if so which is the best version to download in
order to get the measure tool?  I ask because I am on XP, and I prefer
not to have to install large pieces of software unless I know that I
have to.

Thanks for any advice.
