在Windows XP上安装wxPython后,“import wx”失败

http://downloads.sourceforge.net/wxpython/wxPython2.8-win32-unicode-2.8.9.1-py26.exe

当我运行Python并尝试导入wx时,我收到以下错误：

C:Program FilesConsole2>python
Python 2.6 (r26:66721,Oct  2 2008,11:35:03) [MSC v.1500 32 bit (Intel)] on win32

>>> import wx
Traceback (most recent call last):
  File "<stdin>",line 1,in <module>

    import _core_
ImportError: DLL load failed: This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.

我已经尝试删除wxPython并再次安装,我得到了同样的错误.我该如何解决这个问题？
