安装netCDF出现了问题,请求帮助,在线等

我是Windows系统 下载了ScientificPython-2.4.9.win32-py2.4的安装程序,运行时出现了以下错误提示
Fatal Python error:can't initialize module Scientific_netcdf
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
说我没初始化,不知为什么,请高手指点
