org version under Windows 7

[Giovanni Ridolfi <giovanni.ridolfi@yahoo.it>]

Hello everybody (especially Achim Gratz ;-)

I'm back. I'd like to install org on my Windows 7 machine, but

I have some constraints:
- I am not the Administrator 

- I cannot use make 

- I cannot use git


So
1   I downloaded from http://orgmode.org/w/org-mode.git
    the last git snapshot (c75120aa71257604....)
2  un(tar-zipped) it
3  As suggested by Achim a month ago,
    in my scratch buffer I evaluated
    (let ((generated-autoload-file "c:/Users/me/emacs-o/org/org-install.el"))
     (update-directory-autoloads "c:/Users/me/emacs-o/org//lisp"))
messages in the Message buffer were:

Saving file c:/Users/me/emacs-o/org/org-install.el...
Wrote c:/Users/me/emacs-o/org/org-install.el
nil

So this seems not to be the way to set the version

4. Then I run emacs:
    (as suggested in http://orgmode.org/worg/org-hacks.html
>c:\Users\me\programs\emacs\bin\emacs.exe -batch -Q -L lisp -l org/UTILITIES/org-fixup.el --eval '(org-make-org-version "7.8.11" "c75120aa71257" "blabla")'

but the command ended with: End of file during parsing

and, obviously,  M-x org-version says: Org-mode version N/A-fixup 

5. then I followed the instruction with the defvars and evaluated my/compile-org
     but the result was the same.

what can I do?

thank you in advance,

Giovanni
