OK, I rsynch'd the current TeX Live installation suite while eating 
dinner, and have just launched "install-tl-windows -gui tcl".  There 
were a few oddities (it appears to ignore <return> as a completer, 
requiring an explicit click on a button instead) but then I hit a major 
problem — I cannot see where to configure the locations of the TEXMFVAR 
and TEXMFCONFIG directory hierarchies. With the previous installer I was 
able to configure these as X:\TeX\Live\<Year>\TeXMF\Config & 
X:\TeX\Live\<Year>\TeXMF\Var — how should I accomplish that with the new 
one, please ?
