Many thanks for your reply, Hans.

A complete install has revealed the real cause of the slow download: the
antivirus software (that works like crap).

The time that I thought it was downloading each single file, it was
really analyzing it.

Even worse, when the AV software didn’t like the contents of the file,
it saved an empty file (I have seen it with text and PDF documents).

I had a backup copy, so it updated it (manually) with what a new install
for Win64 (which I got in Linux64).

curl is installed in both Linux and Windows (and there was no secure
install on any of them).

And according to lines 634-640 from mtx-install.lua, if curl isn’t
installed, the installation script should quit:

  if environment.argument("secure") then
    usecurl = checkcurl()
    if not usecurl then
      report("no curl installed, quitting")

Or what am I missing here?

Many thanks for your suggestion, since it helped to discover the real
cause of the non-working update.
