# Install MikTeX
#
# This uses MiKTeX basic installer (setup wizard).  MiKTeX is installed only
# for the current users, which avoids problems with per-user and system-wide
# installations going out of sync.  This way one may install a concrete
# version of MiKTeX, which is not the latest one (one may update the
# database below, but not the packages).  This is was used to get
# installation of 21.6 when 21.8 was crashing.
#
# This installer does not work in a docker container servercore image, because
# it uses DLLs/features not present there, but it works in the full server
# image.
