mlabwrap setup query

I happened to stumble upon an answer posted by user brentlance regarding the linking of Matlab to Python, and was wondering if I could ask the community for some advice regarding the initial setup of the mlabwrap module.

I'm on Windows 7 32 bit, using Matlab R2012a and Python 2.7 (from the Python(x,y) scientific computing package). When I try to run:

python setup.py install

in the malbwrap directory, the console returns a very large error, as presented:

WINDOWS SPECIFIC ISSUE? Unable to remove c:\users\nathan\appdata\local\temp\tmpv
tzipc; please delete it manually
[Error 32] The process cannot access the file because it is being used by anothe
r process: 'c:\\users\\nathan\\appdata\\local\\temp\\tmpvtzipc'
