mlabwrap setup query

Question

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'

In response to various other issues, I've thus far tried the following:

1. I followed the installation guide posted here
2. Installed Microsoft VS Express 2010 and SDK version 7.1
3. Set the SDK C++ compiler to the default in Matlab
4. Pointed the msvc9compiler.py script (C:\Python27\Lib\distutils\msvc9compiler.py) at the Common Tools folder for my VS Express install in order to avoid an 'unable to locate vcvarsall.bat' error, as described here.

Any help you guys could provide would be greatly appreciated. Many thanks.
