OK, thank you for that feedback/suggestion Siep.  If I use a portable 
installation, I remember the installer warning me that it might modify 
some of my pre-specified locations.  In what circumstances would it do 
that, and could it still share C:\TeX\Live\TeX-MF\Local, from where my 
(mandatory) support for Hebrew originates ?  And is there a tracing 
option by which I/we might learn more about why TLSHELL is (apparently) 
failing to start TLMGR ?  I find that if I launch it from the command 
line (as "tlshell --debug"), it demands privilege elevation.
