【求助】拜求：matlab安装失败原因

[顶针儿]

安装到24%是出现以下信息：

There was an unexpected exception:

oversubscribed dynamic bit lengths tree

More information can be found at C:\WINDOWS\TEMP\mathworks_installer.log
点OK后，又SKIP了CD2，CD3后出现：
There was an error writing out the installed file list:C:\MATLAB701\uninstall\productdata (系统找不到指定的路径。)

求求大家了，我都试装了好几个盘了，还是不行，急啊！！！
谢谢先！！！
