py2exe can't find msvcp90.dll

I'm working on converting a simple GUI script written with Python 2.7 and Pyqt4 into a standalone executable using py2exe. I keep getting "no such file exists" errors, and I've managed to fix a few, though this one seems stubborn. It can't find msvcp90.dll, and returns an error message with a short traceback to distutils and then back to my py2exe script, which isn't very enlightening. I've installed the MS C++ redistributable runtime, as recommended in

py2exe fails to generate an executable

but my script still can't locate the .dll. Below is my py2exe script, with the name of my script blocked out:

from distutils.core import setup
from py2exe.build_exe import py2exe
import sys, os, zmq

sys.argv.append('py2exe')

os.environ["PATH"] = \
os.environ["PATH"] + \
os.path.pathsep + os.path.split(zmq.__file__)[0]

setup(
    options = {'py2exe':{'bundle_files':1,"includes":["zmq.utils", 
            "zmq.utils.jsonapi","zmq.utils.strtypes"]}},
    console = [{'script':"#######.py"}],
    zipfile = None
)

I've already fixed an issue with zmq (which isn't ever used by my script, or my GUI, for that matter, as far as I know). What am I doing wrong?
