Yes, because otherwise you can get this:
I have no idea what has been updated, but what's for sure is that the
compilations with LyX don't work anymore now ! (messsage : pdflatex
program ended with error).
There is a bug in MiKTeX that causes to break LaTeX completely in some
cases. The new Win installer includes a workaround from the MiKTeX
developer.
Installing LyX again using the new installer should fix your broken MiKTeX
However, I asked you to check if you get a virus warning when installing
only MiKTeX? If yes, this could explain the false positive for the LyX
installer because the bundle installer extracts the mikxtex installer
even if miktex doesn't need to be installed. (The miktex installer will
unnecessary deleted afterwards.)
