Should be fixed now, please test.

The use case with emacs.exe being a symlink to another directory is
not yet supported on Windows, I will add that later.  (It's a bit
tricky, as at this early stage of startup the file names are still
unibyte strings in the current system codepage, so many file-name
related functions will not work as expected.  But using symlinks to
executables is relatively rare on Windows, so I thin we can wait for
this for a few more days.)
