Error using VBScript in BGInfo "Variable is undefined: 'WScript'"

Question

I'm an amateur VB scripter. I'm making a script to check to see if one of two files exists, and if so, give a flag that says "Installed". If neither file exists, flag "Not Installed". Here is my script...

Option Explicit
DIM fso    
Set fso = CreateObject("Scripting.FileSystemObject")
CreateObject("WScript.Shell") 

If (fso.FileExists("C:\Program Files (x86)\Dell\KACE\AMPAgent.exe")) OR (fso.FileExists("C:\Program Files\Dell\KACE\AMPAgent.exe")) Then
  WScript.Echo("Installed")
  WScript.Quit()
Else
  WScript.Echo("Not Installed")
  WScript.Quit()

End If

It works when I run it in Windows 7. When I add it to BGInfo, it throws up this error...

Error evaluating scripted field 'KACE'

Microsoft VBScript runtime error

Line 7, position 2

Variable is undefined: 'WScript'

[OK]

I think I just need a way to define or call WScript to action since it's obviously not doing it through BGInfo on its own, and what I did isn't working. I haven't seen anything to help with this particular problem on StackOverflow already.

Any thoughts?

Would be useful to mention what BGinfo is, for us that don't know. Info here: technet.microsoft.com/en-us/sysinternals/bb897557.aspx. Good first post! — Rots

Thanks for the tip! I noticed yesterday that I always seem to find my answer on StackOverflow, but I had never joined it. This place is my goto place now. I'm glad my first Q&A go-round went well. :) — MaxKorban

BGInfo implements its own scripting host and doesn't appear to emulate the WScript object. Browsing some snippets I found on the Internet, it looks like just plain Echo works inside BGInfo. A snippet:

On Error Resume Next
    call WScript.Echo(strReturn)    'for cmd line
    call Echo(strReturn)    'for BGInfo
on error goto 0

Note how On Error helps to make it work either way.

+1. You beat me to it. I just found it in Mark's article here and was writing the same thing.

That worked perfectly! I also removed the quit lines since they seemed unnecessary, and it tested perfect on every test machine. Thank you very much for your help!
