How to fix this ImportError: no module named win32api? (win32api path variable)

I am new to programming and the world of computers. I am trying to study biomolecular modeling using MMTK.

I run it on Windows 7 and I already installed this software:

• python 2.5.4
• NumPy-1.6.2-win32-SUPERPACK-python2.5
• netCDF4-0.8.2.win32-py2.5
• ScientificPython-2.9.0.win32-py2.5
• 2.6.0.win32-module IOC-py2.5

When I run this protein.py mmtk sample, everything seems to be OK. It shows the number of 1000 steps of the process.

But when I run the script method with view, for example:

from MMTK import *
molecule = Molecule('water')
molecule.view()

Then I get this error:

Traceback (most recent call last):
File "C:\Users\BIOCHEM\Desktop\mmtk\mmtk_water.py", line 4, in <module>

File "C:\Python25\Lib\site-packages\MMTK\Collections.py", line 495, in view
