'Z:\\LocalApps\\examples', 'Z:\\LocalApps\\python\\python24.zip', 'Z:\\LocalApps\\examples', 'Z:\\LocalApps\\python\\DLLs', 'Z:\\LocalApps\\python\\lib', 'Z:\\LocalApps\\python\\lib\\platwin', 'Z:\\LocalApps\\python\\lib\\libtk', 'Z:\\LocalApps\\python', 'Z:\\LocalApps\\python\\lib\\sitepackages', 'Z:\\LocalApps\\python\\lib\\sitepackages\\Numeric', 'Z:\\LocalApps', 'Z:\\LocalApps\\python\\lib\\sitepackages\\win32', 'Z:\\LocalApps\\python\\lib\\site-packages\\win3\\lib', 'Z:\\LocalApps\\python\\lib\\sitepackages\\Pythonwin', ' 'Z:\\LocalApps\\python\\lib\\site-packages\\wx-2.6-mswansi' BUT when the error is thrown out it is: C:\Program Files\Python24\Lib\site-packages\win32com\client\dynamic.py... -- http://mail.python.org/mailman/listinfo/python-list
