I found the reason why the Windows installer failed:

if os_name=='windows' and 'install' in sys.argv[1]:     # *not* argv

However, there is no need to call the post-install script at all in the 
setup-script.
This is done automatically by distutils.

With the attached versions of setup.py and 'ipython_win_post_install.py' 
I can
run a *complete* and *successful* installation/ deinstallation cycle.

For the moment I just want to document the facts and the current status. - I
attach portions of my work-log:

2004-06-20 12:31:28

o Prepare a *minimal* version to send to FP and the mailing list.

o Run 'bdist_wininst'.

o Install 'IPython-0.6.1.cvs.win32.exe'
 - Finished w/o a glitch; i.e.
 - C:\Programme\IPython\IPython.py created.
 - Menu 'Start > Alle Programme > IPython' created empty.

o Running C:\Programme\IPython\IPython.py in IDLE w/ 'Run Module' fails w/

### Begin of IDLE Output ###

 >>> ================================ RESTART 
================================
 >>>

Traceback (most recent call last):
  File "C:\Programme\IPython\IPython.py", line 26, in -toplevel-
    import IPython
  File "C:\Programme\IPython\IPython.py", line 27, in -toplevel-
    IPython.Shell.IPShell().mainloop()
AttributeError: 'module' object has no attribute 'Shell'
 >>>

### End of IDLE Output ###

o De-Install 'Python 2.3 IPython-0.6.1.cvs'
 - Finished w/o *any* glitch.
 - However it reported that 1 files or directories could not be removed.
  * C:\Programme\IPython\ - Most likely because I had the script 
'IPython.py'
    open in IDLE.

o Remove C:\Programme\IPython\ manually ...


2004-06-20 12:49:46

o Proofed my theory w/ another installation/ deinstallation cycle.
 - Everything got properly removed ...

### End of work-log ###

But the way it looks like, this is just the start of the road to a working
Windows Installer. - I'll start a follow-up discussion in a future mail.

Regards,
    Viktor
