[Tex/LaTex] Tex Live 2015 on Windows 10: errors during update in Tex Live Manager

fmtutiltexliveupdatewindows

In a brand new installation of Tex Live, the first time I tried to update installed packages (a few weeks after installation), I got many errors similar to the following:

fmtutil-sys --no-error-if-no-engine=luajittex --no-error-if-no-format --byengine uptex failed (status 255), output:
c:\texlive\2015\texmf-dist\scripts\texlive\fmtutil.pl: Unexpected non-option argument(s): fmtutil
Try "fmtutil --help" for more information.
C:\texlive\2015\bin\win32\runscript.tlu:663: command failed with exit code 255:
perl.exe c:\texlive\2015\texmf-dist\scripts\texlive\fmtutil.pl fmtutil --sys --no-error-if-no-engine=luajittex --no-error-if-no-format --byengine uptex

Many errors like this one regarding uptex occurred concerning pdftex, xetex, tex, etc.

This first approach to Tex Live is not very attractive, is it advisable to go with MikTeX since I'm under Windows?

It is a bug in TeXLive, should be fixed in tomorrows update or try it yourself by modifying the code.
