Executing Package from a batch file gives error

I am executing a SSIS package through bat file using the following command:

"C:\Program Files\Microsoft SQL Server\100\DTS\Binn\DTExec.exe" /f "C:\Test.dtsx" /ConfigFile "C:\testconfig.dtsConfig"

I get the following error:

To run a SSIS package outside of business intelligence studio you must install standard edition of integration services or higher.

I am using Visual studio 2008 and here is the version I got from help>about in visual studio.

Microsoft SQL Server Integration Services Designer
Version 10.0.5500.0 ((Katmai_PCU_Main).110921-2358 )

Should I have a install version greater than this?

If yes,Can I execute the package in a bat file using xp_cmdshell?
