The fns-VERSION.el is getting installed in the correct folder where the
emacs.exe resides (NO BUG).
The problem is, if environment variable EMACSPATH is set to some other
folder or list of folders as in PATH variable, "exec-directory" has the
first entry from EMACSPATH.

Ex:
Case where I have GNU Emacs installed under D:/GNU/emacs and have
"gnuserv.exe" and other binaries in
"D:/GNU/bin":

cmd>set EMACSPATH=D:/GNU/bin;D:/GNU/emacs/bin
cmd>emacs
In Emacs session, the value of "exec-directory" is "D:/GNU/bin" but Emacs
executable is in "D:/GNU/emacs/bin"
and "fns-VERSION.el" file is also in "D:/GNU/emacs/bin" folder.
The value of "invocation-directory" is "D:/GNU/emacs/bin" which is
correct.

The same behavior is shown in uninstalled Emacs exe too found in
"emacs-21.2.93/bin/emacs.exe" after build.
