菜鸟求助～安装matlab出现的小问题～

[xxx267]

安装好程序后，点击“Simulink”按钮后，“command window”出现如下警告：
Warning: Error evaluating 'D:\Program Files\MATLAB\R2008a\toolbox\rtw\targets\c166\c166\slblocks.m'. Error
Message: The specified super-class 'ProductInfrastructure.ProductInfoGeneric' cannot be found on MATLAB's search
path or contains a parse error.
Warning: Error evaluating 'D:\Program Files\MATLAB\R2008a\toolbox\rtw\targets\mpc555dk\mpc555dk\slblocks.m'.
Error Message: The specified super-class 'ProductInfrastructure.ProductInfoGeneric' cannot be found on MATLAB's

请问这个对matlab的正常使用有影响吗？如何消除这几警告？先谢谢各位大侠了！
