Yamamoto-san, I found the problem and solution.

I checked Windoes Registry and found there is no reg for Emacs. It's the
same case for Emacs 22 and Emacs 23 (all built with recent cvs source).
I checked mew.c and know it depends on reg value of emacs_dir.

I checked addpm.c code, and found its usage is

usage: addpm [-q] [emacs_path [icon_path]]

so it means emacs_path and icon_path are both optional.

But seems it's not true.

Installation of cvs emacs (head and unicode-2 branch) does run
addpm.exe. But it only creates a shortcut to runemacs.exe, and no
registry item is added.

So in cmd shell, I run
addpm c:/emacs

and it added all registry items, and mew installation worked.

So seems it's a bug with Emacs code.

At last I have two suggestions:
1. Change line 47-48 of 00readme.w32 from
      C:\> cd emacs-21.3\
      C:\emacs-21.3\bin>addpm
to
      C:\> cd emacs-21.3\
      C:\emacs-21.3\bin>addpm  C:\emacs-21.3

or maybe better to:
      C:\> cd emacs
      C:\emacs\bin>addpm c:\emacs

since many users use cvs emacs or emacs-unicode-2.

2. Change mew.c to use emacs_dir environment var before registry item.
Seems mew.c is only dependent on windows registry.

Now emacs can run well without any registry entry set. If mew can run
well with environment var, it will be a cleaner way.

I'll look into mew configuration problem and report back.

Thanks for your help.
