SSIS task failed to load(Script task)

Hi,

I am running a SSIS package using a bat file. When I run the bat file it gives the error ,'The task has failed to load.The contact information for the task is " " '. Can you let me know how to resolve this?

I am running this on Sql server 2008 . I have seen previous posts with same error saying, the problem is with the installation of SQL Server .What components should I install additionally or what are the components that did not install correctly?

Thanks
