Running Windows Batch Files in Test Complete(VBscript)

I am trying to execute bat file through code instead of using "TESTED APPS" as below..

--------------

sAutoAppPath = "E:\AutomationDir\Applications\InDMSApp_QA\bin\start_dms.bat"

Call Sys.OleObject("WScript.Shell").Run(sAutoAppPath )

and

Call Win32API.WinExec(sAutoAppPath, SW_SHOW)

--------------------------------------------------------------

WHile executing the above code i am finding error "System cannot find the file specified"

Can anyone please suggest the solution to execute the Bat file through the code?

Thanks in Advance..

Kavan..
