You have installed the recommended Python and win32all libraries but you still see a number of error/traceback messages in the script log panel and every time you run something from the script editor, such as:
#INFO : "4000 - exceptions.AssertionError: This module has already been processed by this process"
You can prevent those asserts by following these steps:
Open %PythonPath%\Lib\site-packages\win32com\client\gencache.py in a text editor.
Search for the following phrase:
"This module has already been processed by this process"
Comment out the following lines:
# assert not mod.__dict__.has_key("_in_gencache_"), \ # "This module has already been processed by this process"
You will now be able to script in Python with the version of Softimage that you are using.
