[MATLAB基础] matlab 2009a安装问题

[xugogo]

matlab2009a在Windows xp下安装到30%时 出现The following error was detected while installing Filter Design Toolbox:

invalid entry size (expected 299 but got 786845 bytes)

Would you like to retry installing Filter Design Toolbox? If you press No, the installer will exit without completing the installation. More information can be found at C:\DOCUME~1\fox\LOCALS~1\Temp\mathworks_fox.log
急求各位大侠支个招
