First of all, many thanks for your W32TeX!  I also use your TLW64
binaries on top of my TeXLive 2015 and my observation is also that
TeXLive uses its own binaries everytime fmtutil is triggered upon an
update.  Hence, I have to issue

    fmtutil-sys --all

manually in order to match the fmt-files to TLW64 binaries which come
first in my PATH.

Best, Arash
