You use some form of windows command prompt and you do something to fix the 
PATH to include the directory where nona.exe etc. are installed.

There are various ways to create an icon and/or a right click menu choice 
that will open all that easily from then on (vs typing the command to 
change the PATH  each time you start a cmd prompt to work on this).
You could also use control panel to permanently change PATH so Hugin 
related exe's are always on your path.  I use my computer for too many 
different things and hate PATH pollution, so I wouldn't do that myself.  
But if using Hugin is a significant fraction of the purpose of the whole 
computer, then including it in the permanent PATH is the simpler choice.

There are multiple (better) alternatives to the basic cmd prompt and 
multiple ways to set up each to have a customized launch for specific 
purpose.  So too many choices: which usually means just do it some simple 
obvious way while knowing that if it is worth trouble to make it better, 
you can.

That is a sub-topic I'd really like to understand, since I'm fighting many 
situations in which the tiff is very fuzzy compared to jpg.

I have seen about as many situations in which the colors look better when 
viewing a tiff vs. jpg as the opposite.  Each viewer has its own rules for 
the non linear translation from 16 bit intensities to 8 bit intensity for 
display on your monitor.  They don't seem to be just throwing away the low 
bits.   Depending on the photo and the viewer, that mapping can make the 
picture look much better, including increasing the contrast between two 
colors that are adjacent and look better with more contrast.  A big 
advantage of working in 16 bits is the ability to adjust the final mapping 
to 8 bit AFTER stitching.  Maybe that is all you mean by "more contrast" 
and "sharper".

It might also be possible that the jpg compression is actually blurring 
edges etc compared to raw.  But that is opposite to my own experience (thus 
a subject I'd like to be told more about).

Disk space is cheap.  So while I have some similar objections myself to 
keeping around lots of tiff files, I think my own use pattern is odd and 
most other people should not care about that waste of disk space.  Am I 
missing something?  Maybe that is another subtopic I'd appreciate having 
explained.

so then i thought maybe i can get a bit more out of the jpg by using

I hope one of the experts explains some of that here.

I have never had any decent mental model (despite rereading Hugin 
documentation many times) of what high vs. low dynamic range actually means 
as a concept in Hugin's processing.  Of course, I understand what it in 
photography,  but that doesn't tell me what selecting it in Hugin actually 
causes Hugin to do differently.
