Yes, it was meant literally. But I have never said that TL installer
has set that path :) :) :)
(There is some weird thing going on that I still don't understand, but
is not related to TL. When I open a new cmd, it sometimes holds TL
binaries in PATH and sometimes not, so I sometimes have to set the
path manually. But I won't spend any time trying to figure out why
that happens since it might be any component of software that's
interfering. I'm using a virtual machine with single windows and some
imitation of start menu.)

You can try to set the path literally to the same value as mine if you
want to test why binary search is failing. But there is nothing wrong

No, I mean this one:
(but I need to check why the date of file is so old.)

I'm not sure about the current state of luatex, but last time we tried
it was no problem to put a statement
os.execute('rm -rf something')
inside a TeX document. And Reinhard might also be right about
security. In my view it is OK to first search in path and then in
current directory, but searching in current directory at all and in
"path that is a bit wrong, but still works for windows" might still
I'll test Taco's update.
