thinstall vdm client with autologon script

i'm having trouble packaging vdm client with a auto-logon script. i

first captured a clean vdm client thinstall package then did the

following:

• run the auto-logon script and it will run the vdm client package and connect me directly to the desktop

• added
       the script to c:\program files\vmware\vmware thinapp\captures\vmware
       vdm client\  (same directory as build.bat and package.ini)

• run build.bat to package the script with vdm client

• run the newly created package and get error:

• Script Error

• Source: Microsoft VBScript runtime error

• Description: Variable is inderfined: 'WScript'

• File c:\program files\Thinstallplugin\test.vbs

• Line: 4, Char: 0

here is the content of the script:

Option Explicit

Dim objShell

Set objShell = CreateObject("WScript.Shell")

objShell.Run "wswc.exe -serverURL xxxxx.com -userName xxxx -password xxxx -domainName xxxxx -desktopName xxxxx -screenFull"

WScript.Quit

can anyone help?
