Actually, I don't think reboot is necessary on NT, not for setting the
environment variables anyway.   

Instead of reboot you can lauch Control Panel/System, view the
environment page, you'll see the new environment variables from
registry there.
Just press Ok to close System, and presto, your environment
variables are in effect.

Doesn't work for me ;-(, see below.

I gave it a short run-a-round, but unfortunately no go.

PythonPath is not set up correctly, it omits the Imaging/Lib
directory.  

I tweaked it from the registry to read

[HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\1.4.0\PythonPath\Imaging]
@="d;\\PythonWin\\Imaging;d:\\PythonWin\\Imaging\\Lib;d:\\PythonWin\\Lib\\Tkinter"

Another option would be to replace the "d;\\PythonWin\\Imaging"
with "d;\\PythonWin\\Imaging\\Lib" and move the dll files from Imaging
to the Lib directory.  This would be cleaner in my mind.

After the path modification viewer.py manages to run.  It however
terminates to a weird traceback: 

[d:\pythonwin\imaging]..\python Scripts\viewer.py Images\lena.gif
Traceback (innermost last):
  File "Scripts\viewer.py", line 36, in ?
    im = Image.open(filename)
  File "d:\PythonWin\Imaging\Lib\Image.py", line 467, in open
    init()
  File "d:\PythonWin\Imaging\Lib\Image.py", line 84, in init
    for f in os.listdir(p):
nt.error: (3, 'No such process')


This looks weird enough for me to quit at this point and let the specialists
step in ;-)

Looking forward to that.
