importerror all 3rd party modules

[nyiann]

Hi,

Brand new to python.  I am trying to install the py2exe modeule, and when 
I run scripts (simple ones I've made, and examples) I get an importerror. 
At the python command line I type:
import py2exe
and get: 'ImportError: no module named py2exe

So installed everything on my laptop (windows me) and it all works fine.
Has anyone seen this before?  Am I importing the module incorrectly?  Are 
there platform specifics issues when installing 3rd party modules?

Any suggestions appreciated,
N
