python.exe Unable to locate Component - pywintypes23.dll not found
This Error Reference applies to:
Plone 2.1.x, Plone 2.0.x

Any audience.
Zope with Plone on Windows pops up a alert window with the message above.
Reason
The python version has a problem to find a function in the DLL when importing win32api module of Python windows extensions. This module is loaded by PortalTransforms Product for Archetypes 1.3.x shipped with Plone 2.1.x.
Description
PortalTransforms automagically loads available transforms from one mimetype to another and checks it's platform running on for available features.
The word_to_html transform looks for availablity of COM by importing win32com. If this fails the transform is just not available - no reason to worry about. The test for COM availibility itself normally shouldnt affect any user interaction. Unfortunally Windows pops up a dialog-box at this point.
After clicking ok, the Plone/Zope continues starting and works as a production ready application server. It just hasnt a Microsoft Word .doc to HTML converter available.
Solution:
By code manipulation
Surpress checking of word_to_html by commenting the line 20 word_to_html in File 'Products.PortalTransforms.transforms.__init__.py:
modules = [
'st', # zopish
'rest', # docutils
#'word_to_html', # uno, com, wvware
'safe_html', # extract <body> and remove potentially harmful tags
'html_body', # extract only the contents of the <body> tag
'html_to_text', # re based transform
And in Products.PortalTransforms.libtransforms.utils.py fixate the check for WIN32 to True:
from sgmllib import SGMLParser #try: # import win32api # WIN32 = True #except ImportError: # WIN32 = False WIN32 = True class MissingBinary(Exception): pass
By Windows manipulation
Append the ZOPE_HOME\bin directory to the system-path. This does not work in every case if Zope is started as a service.

python.exe Unable to locate Component - [..] pywintypes23.dll not found [..]
I am running: - WinXP Prof, service pack 2 - Python 2.3.5 and 2.4.3 - Zope-2.8.1-final
I was having the same problem. I found that I had an older version of pywintypes23.dll (ver 2.3.0.163) in C:/windows/system32 than the copy (ver 2.3.208.0) that came with plone.
I did the following : - renamed the old version to "old pywintypes23.dll" - copied the newer version from the plone install folder (c:/program files/plone) to the system32 dir - rebooted - ran the plone install again (Plone-2.1.3-with-Zope-2.8.exe)
The install did not throw this error this time.
