ImportError when import pylab

hi list,

I’m new to matplotlib. My environment is WinXP, PythonWin 2.6.2, NumPy 1.3.0, matplotlib

import matplotlib.pylab as pylab
Traceback (most recent call last):
File “”, line 1, in
File “D:\Python26\lib\site-packages\matplotlib\”, line 253, in
from matplotlib.pyplot import *
File “D:\Python26\lib\site-packages\matplotlib\”, line 75, in
new_figure_manager, draw_if_interactive, show = pylab_setup()
File “D:\Python26\lib\site-packages\matplotlib\”, line 25, in pylab_setup
File “D:\Python26\lib\site-packages\matplotlib\backends\”, line 8, in
import tkagg # Paint image to Tk photo blitter extension
File “D:\Python26\lib\site-packages\matplotlib\backends\”, line 1, in
import _tkagg
ImportError: DLL load failed: cannot find the module

I searched the web and it’s said because of lack of msvcp71.dll, but there is already on in my C:\windows\system32\

anyone can help?
